I have spectrum pro and i like because 1 you can mod it to have the one short anttenae and it is easier to find spectrum recievers if you have more cars. Airtronics is like 100 bucks for a reciever and spectrum pro is 89.99 and normal which works with pro is 79.99 but used you can get the spektrum recievers easy for 50-60 bucks. I have bought 2 off of here.
The airtronics is alittle nicer cause it has a blue light although i heard of someone the other day having issues with theres.
