I use a Futaba T8J 2.4 radio and I am very happy with it. It sells for $279 on TH and if you are a member, you get free shipping and $30 off. Plus their 6 ch receivers are on sale until end of year for $29!...... I ordered 5 of them because regular price is $44.
I also fly with my old 72 radio and never had an issue with either. Also 72mhz receivers are dirt cheap now days.....so either way, you should be good with either.
