1) You will crash
2) You will be spending money
3) If you stay with the hobby, you will be buying/building more complex and more expensive aircraft and the gear to fly it

I build and race 1/8 scale unlimited hydroplanes. The average engine costs $600 new, not including exhaust. To put a boat on the water will run between $1500 and $2000. Based on that, I would be looking at the best radio that meets my requirements and not worry about cost. If I were to price out my present radio system it would look like this:
Transmitter-Futaba 4PLS $250(when I bought it, now $180)
Transmitter Battery Pack-Lifesource LiFe 6.6 volt 1900 MAh pack $35
Rudder Servo-Futaba S9156 high torque digital $130
Throttle Servo-Futaba S3050 digital $60(no longer available)
Receiver Battery Pack-NR4J 4.8 volt 600MAh flat pack $18
Of course, you have to charge your batteries so you can add:
Hobbico Accu-cycle charger $120
Hobbico Lifesource balancing charger $35
If you add all that up, just to race one boat cost me $645, JUST FOR THE RADIO AND ASSOCIATED ADDITIONAL REQUIRED ITEMS
