Right, I remember seeing one in an RC shop and it was in the hundred dollar range.

I saw one recently in Sweden in some computer shop (not even RC shop), they had transmitter - 4+1 channel and receiver with 4 servo outputs (no servos included) and one 0V/5V output (the +1) for the ~50$ ... 300m range iirc. ... I also saw few models in Germany on the high end side (32 channels .. 24 analog and 8 digital) that go over 4 digits...

They are pretty expensive new, but ebay, flea markets, craigs list and the like can sell you ones that work just fine for pretty cheap. There are also cheaply made ones on some direct from china sites, I haven't used those, but theyre a cheap option as well.

whoa3.... I think the guy's just wanna start.. Why don't you use the one paired with a pt2272/pt2262 for the receiver/transmitter? They're like "push switch number one, LED number one turns on, push number 2,......."

You don't even need a PIC or any uC.
Costs around 2 bucks for each IC, I think.
