Hitec Laser 4 or Laser 6 is about $120-$160US and a Futaba Skysport 4 or 6 should only cost about $130-$180US. These are for the new systems including TX/RX, batteries, servo's, & charger. They're available in both 75mHz & 35mHz.
I personally use the Skysport 4 & 6 units on my trucks. 75mHz, works pretty well. I've just recently acquired a Hitec Laser 4. I haven't had a chance to test it yet, so I can't vouch for it (but it looks to be a good radio).
