Thanks for the replies guys
I've had no luck in finding a 3GR with RX for a low price. JE Spares seem to be the cheapest I can find at £198.99. It was the same a few years ago when I bought a set. Futaba seem to hold their price.
It looks like I'm going to have to spend big money on a TX set, but the Etronics has to go for sure.
