Giantcod and T9hobbysport both do them in the UK, less than £25 and no issues with duty and admin fees. Agree with Spoolio, a great receiver that works. I haven't had any issues using it in 12th and GT10 cars, and they are fussy about having good radio gear with all the electrics so close together.
I've used the same philosophy as the 'plane guys and the original Futaba receiver - one aerial at 90 degrees to the other. I put one aerial up the mast/tube, and tape the other along the chassis. Works really well. HTH
