Hey. I just wanted to ask if 120AUD (approx $85usd) is a good price for the following:
Steel Gears:
2 x 57.5gram servos, Torque: 7Kg/cm at 6v, Speed: 0.2sec/ 60° at 6V (at no load)
2 x 52gram servos, Torque: 9kg/cm ,Speed: 0.18sec/60 degrees
1 x 46gram servo, Torque: >=7.0 Kgf.cm at 4.8V, Speed: 0.17 sec / 60 degree at 4.8v
Plastic Gears:
2 x 9gram servos, Stall Torque: 1.7kg/cm, Speed: 0.1sec/60 degrees
1 x 100gram servo, Torque: >=19 Kgf.cm at 6v, Speed: 0.19 sec / 60 degree
I'm pretty sure they are decent quality at the very least.
I'm just not sure about the price or what i'd expect to pay for the above as i don't want to be ripped off.
So is $85USD a good price for 8 servos above?
(Can't wait to get started on some robots :))
Thanks Guys ;D.

If you can't get them cheaper they're cheap. If you CAN get them cheaper then why ask.
It appears that most of the RC/Robotics business is in the USA and we're on the wrong continent. We're not on the same (wrong) continent as I'm in Europe and I always see huge price difference betwen products sold in the USA and products available locally. Transport is too expensive for individual parts and European sales tax and import taxes don't help at all! Today I wanted to buy an "PING" sensor from an USA reseller and they quoted me $100 for the transport :-X
Back to your servos. If you're getting 8 servos for a total of $85 then they're cheap servos. If you're happy with the quality go ahead and get them - you'll have something to play with and you'll now exactly what you need for your next purchase. Brand name servos (Futaba, Hitech) are much more expensive, look around.

Thanks heaps =).
I'm aware they wont perform nearly as good as brand name ones but as you said this is a beginner project and i'm just looking to get started.
And i agree with you so much about the wrong continent bit... it's so difficult to find anything in Australia, everything is in the U.S and shipping is nuts -.-
I've found brand name servos in australia but they are like double what they would cost in the U.S which is nuts!
Anyway thanks for the reply just wanted to see if i was getting ripped off for no-brand servos.
Good luck finding some "proper" (sane) prices for your "ping" sensor.

Cosmin, too bad you got on the forum after I left the country. Amongst other things, I had 4 Ping)) sensors for sale at $25 each because I needed money to get to Canada. In about a month I'll send a package to my brother in Sibiu. If you don't have one until then, I can send you one in the same package, so you don't have to pay that much shipping.
-
He-he, you have a brother in Sibiu. I'm from Sibiu :D The world is so small (really).
Thanks very much for the offer! Actually I'm planing on making a nice big order of $1500 to somewhere so the shipping costs go down (proportionally). Unfortunately it's difficult because I want some robotics stuff for myself and my brother wants some RC stuff and we can't find them at the same shop. If I can't manage it I'll sure take you up on that offer! Thanks again.

Found an site in UK that has good shipping for all the European Union: http://www.active-robots.com/
I've not ordered the ping but I've ordered a bunch of other stuff.

OMG! You know, I have started a robotic group (RoboSib) at the Electronic Department of the School of Engineering... They won First prise at 2008 national qualifications for the Eurobot competition. If you are still a student, go talk with prof. Ioan Mihu, (tell him you found out abot the group from Gabriel Petrut) they may need your programming skills for this year's competition. They are using PICs for their robots...
P.S. Check out this store in Italy: http://www.robot-italy.com/index.php/language/en (http://www.robot-italy.com/index.php/language/en). Many romanians have ordered from it with complete satisfaction.

If you are still a student
No longer a student. ;) Thanks for the Italian shop link and good luck to the team!
It's amassing how this hobby is finding it's way into the country. There are several robotics clubs at different university-es, and I'm proof it's finding it's way outside the University as well! Also I'm amassed how many people are into the "RC" hobby, and I'm not talking about kids here: grownups with families.

In 2006 I returned to Romania from USA. There wasn't much interest in robotics at that time. After a few online efforts with a Yahoo group, a Artificial Intelligence forum, some advertisement on the RC forums, electronics forums and especially having the national qualification competition for Eurobot held at the Polytechnic Institute in Bucarest every spring, year by year the interest grew larger and larger. I wanted to open a robotics group to teach kids robotics using Mindstorms, but I have found no sponsors at the time. I even wanted to manufacture and sell a robotics kit (ATmega8 based). Just a few months ago another guy said on the www.inteligenta-artificiala.ro (http://www.inteligenta-artificiala.ro) that he wants so do that too. There are even some online robotics stores in Romania, like www.robotul.ro (http://www.robotul.ro) and another one that I think is mostly for RC stuff but also sells robotic parts. So yes, there is a growing interest for robotics, starting from highschool students, all the way to grownups. And I am proud to be a stirring element!
