Connections are similar for multiple servos.

I would like to stay with BASIC, but do not want to pay for the Stamp. So I figured I will use C.

When looking at the AVR, it says that the 'Boot Logger' software is already programmed. What does this mean?

You could use PICBASIC with any PIC microcontroller

but picbasic costs 100 bucks ( however I downloaded it from a torrent website .... ;))

I recommend PIC BASIC

This most likely means the boot loader. It's a program that is always on the chip that makes getting your programs onto the chip easier.

So instead of having to use fancy JTAG equipment, you will most likely need a regular serial port. It's a GoodThing but you will want more information about it obviously.

Which AVR is this btw? I use a Robostix (which is an ATmega128, which is to say an AVR) hooked to a Gumstix and I use the I2C (a more specialized kind of serial protocol) to send my boot loader things and it works out all right.

Yes, Boot Loader. My bad.
I do not remember where I saw it but it was in another post on this forum and I just wasn't sure what it was.
If I can use PIC BASIC with PIC's, then that is something I am going to look into more as I have no real disere to get into programming as I more perfer the electronics aspect of robotics.

The $100 is not bad for PIC BASIC... but what all does that include? I'm assuming that is just a compiler (but hoping that it's a good one).

Does anyone else have any oppionions on PIC BASIC for simple programming?
(By simple I mean that I am not going to try to use it to program AI, nor speech releated, etc. Just a "If this happens, then do this. If that happens, then do that" sort of programming.)
Thanks to all.

Compiler  - http://www.melabs.com/products/pbc.htm
Programmer I use http://www.melabs.com/products/usbprog.htm

PICBASIC is actually pretty complex for the BASIC language http://www.melabs.com/products/pbcis.htm

I personally use PICBASIC Pro, its $250 , but its amazing ! Much more commands and more complex

also, PICBASIC allows you to add assembly code within the BASIC code

Actually, I've seen numerous projects using PICBASIC for speech recognition, AI, and camera equipped robots.

It sound like AVR is a ton cheaper than pic, right? Doesn't the pic compiler cost like $100?

That's exactly I started with AVR (Arduino to be more specific), it's cheap and fairly easy which makes it a great start of a journey through the world of robotics. ;)

This may be just my opnion, but it seems like all MCU's are about the same price. It just depends on wether you pay for the chip or for the compiler or the extra hardware, but in the end I think they all come out about the same.

MCUs do cost the same

Compilers and programmer hardware are the ones that cost money

For PIC mcu the compilers and hardwares cost a lot and for the AVR they are much cheaper
s
But, PICs are easier to get ( free samples while AVR is no longer sample) and there is a wider variety of PICs which are suitable for different tasks.

AVR does not have that wide of a selection

My vote is for PIC micro controllers with PICBASIC compiler
