I'm looking for a radio for my 2nd car (E Stampede). I don't want to spend much more than $60. The ones I've been looking at are the Hitec Lynx & Lynx Sport, Hitec Aggressor, Futaba Magnum Sport & Junior, and JR Python. My other car has an old KO Propo 75 mhz AM system so it'd be great if the new radio equipment were interchangeable with that, but it's not necessary. I'll be just doing backyard bashing, so I don't think FM is that important.

How does the Hitec Aggressor compare with the Lynx? Are JR radios compatible with KO?

Thanks!
