Newbie questions - main one - how cheap can a bot be? Advice please. :)

Hey all!


I had a nice nostalgia hit last night watching a few old recordings of Robot Wars and now I need (yeah, need) to convince some of my friends it's a good idea for us to do our own little robot wars... thing...


Plan was I'd get the basic components and let people put them together and build the chassis, weapons, etc. out of whatever they like. Until I actually started researching this I thought it to be a great idea...


I still do, really.


But I'm already stuck-ish. So far I've determined that for each robot I'll need to get:
- 3 servos (2 wheels, 1 moving weapon)
- a transmitter/receiver pair with 3 channels (channel per servo)
- maybe some gears so people can fiddle with speed vs power
I've got wire and wire strippers so nobody needs to get that, and they can all provide their own batteries, sticky tape, pringle lid wheels, scalpel blade axes, etc.


Everything I research though just raises more questions... for now, just the main one...


1) I figured since you can buy a remote control car for well under a tenner I'd be able to get all the electronic parts for each robot for £5-£10. How painfully wrong is this? >.<


Don't crush my dreams too hard.
Cheers,

edit: off to work now but will have some less boring questions later- promise! >,<
