It is a tough decision, a little like Ford vs Chevy vs the other cars

. I think Futaba's are probably the best, but I think they are too expensive for the recievers and the transmitters for that matter. You should look at how many planes you may have and what type of planes you may want to have.
Spectrum/JR (both use the same type of RX) great selection of bind and fly planes, the radios are afforadable, and you can use the rx from spextrum if you get a bigger jr TX, a 7 channel rx is $99, a 5 channel is $59
Futaba, great lines of product but their 7 channel rx are $99, 6 are $69 and I don't know if hte 4 channel will work with the higher radios, but they are $54.
Airtronics, I think there 8 channel radio is the best deal, and you can get a 10 channel with RX for $400 or so, their 10 channel RX is $149, their 6 is $59.
Hitec has a new Aurora with telemetry (that can tell you real time information about your plane) a 9 channel for $440 with 3 recievers (until end of March) there recievers are $69 for a 7 channel, and $49 for a 6 channel.
It is a hard choice, but for me, I look at the number of RX that I want or would want, and the other features. I currently have about 12 planes in various states and the number of RX price adds up. BUT..... there are a lot of people that get into the hobby and don't last long.
Just my 2 cents
