Futaba Magnum 2peka i think they are called i have one. There nice radios. i think it was $69 but i got a deal on it from the guy at my hobbyshop. I havnt had any problems with it and its my favorit radio i have.
Airtronics MX-3 is a really good FM 75mhz radio within that price range. Its closer to the 100 than the 150 though. I dont think you would mind that. It has all the bells and whistles and can control multiple cars. Check it out.
Here is a kinda cool site where users review kits, engins, radios and pipes check it out. Its Nitro Review.com. See what other people are using and what they think. The reason I say its kinda cool is because people feel they should review a product only if the have it and like it. You will hardly get a negative review. You will get some, but not a lot.
