New to the hobby- Where to get parts on the cheap?

[npolanosky]

So I just realized how cheap I can build a beetleweight, especially if I buy hobbyking ESCs and flash them myself with an ISP programmer. I think I may attempt that first, it's going to be much cheaper and there are a lot more competitions I can compete in. I can basically build a beetle for $40 of electronics..orange rx, 20a ESCs for $8 each, and some $10 motors. Where is the cheapest source of these "1000rpm" gearmotors everyone talks about?

Also, I ordered two botbitz 85A controllers for a larger bot- I'll play with those as well. I think if I get my ASP programmer I will be able to convert my own turnigy ESCs to robot use for $40 instead of $80...so power will become a non-issue.
