I think all 2.4 would help your issue out. For a "budget" radio some of the above mentioned are great deals!

That is the airtronics. It's a nice, cheap radio. I think you can use a 10% off coupon with it and get it for $152 and free shipping since it;s over $100. Maybe give them a call and double check.
Futaba has a nice one as well for a little more($199).
