Hey all!
First post - My name is Brandon. ;D
Well I have been into learning robotics for not too long, but I feel I have covered the basics of electronics.
At this point, I feel I'm going to buy my core hardware (soldering iron, resistors, capacitors, breadboards, etc.)
from Jameco for now on. Their prices are ridiculously low. But their servos seem a bit overpriced...
Do you guys know of any sites which sell servos at a fair price?
Thanks!

This site seems promising. What do you think?
-
I've used servo city before and I am/was quite pleased with their selection and pricing.
-
Well i got my servos off ebay. Futaba S3003s. They have them so you can buy them in sets of 2 or 4 or6 or you can buy them in a singular form.
They also have hitec and other hobby servos.
A very wide selection.

You live in america right?

I recommend servocity. They generally have the best selection/prices.
But don't trust the listed servo specs, they are quite often wrong. Look them up at the manufacturer sites. And they rarely reply to customer emails, so just call for support.

Oh, so sorry for the late replies. After so long I thought I wasn't going to get any replies.
And yes, I live in the US. ;D
Of course I could use Ebay, but I see as a hit-or-miss as to whether a seller is honest
about their product. I'd much rather have a reliable retailer and become a bit more
experienced before I find myself buying from Ebay.

Well, if they have 100+ feedback, sellers wouldn't scam you out of a little servo.

Paranoia... :P

Ok, so in summary, I shall buy from Servo City.
Post Extension - Mini Questions before I buy:
1) Do different servos operate differently when it comes to hooking it up? (not specifications)
2) Which servo do you guys think is 100% "standard", or most commonly used.
I don't wanna do anything specific yet, as I'm still just learning. I have a PICAxe kit that
I still need to learn how to use before I really plan anything.
If I need to make a new post, just holler, and I'll gladly make a new post.

Not unless it states it, rarely.
2) Which servo do you guys think is 100% "standard", or most commonly used.
Well, a very common servo around here is the hs-311, mainly because of the $50 robot... Similar hs servos should do too.
-
Yah I feel stupid...skimming through the robot tutorial mentions that same exact one. I feel hypocritical...
Thanks! Wish me luck!
I'll probably wind up posting up my results...

All servos act differently, sometimes even the same exact model by the same exact manufacturer. Some do 260 degrees, some only 90 degrees, some take 1s-2s PWM, some take 0.5s-2.5s PWM. Rotational speed, torque, expected lifetime, efficiency, all different . . .
They are, however, all controlled using PWM.

The Futaba s3003 is the most popular servo in the RC world where they originated. The HS311 is just some random thing the robot guys got a hold of ;)

I love the Futaba s3003's.I have alwaysed used them and they are suitable for everything i have done so far.
And they are well priced.
