Look on ebay - I found 2 great deals on radios, a new 3pk an a used 3pjs. Its been a while, but if I was looking for a radio I'd start with ebay.

I set up all my rcs on these 2 fm radios. I've never had a glitch of any kind or interference - 2.4 came along too late and changing would be way too expensive with 20+ rcs.
