Thanks for all the replies.

That price for that radio is pretty much average across the different LHS's that i have visited. Approx. $400 AUD for a 6ch computer radio. The list of features is a little daunting - it seems each radio has that little extra that the other does not, however i assume that all the basic functions would be common to all radios (mixes, switches for the ch's etc). I liked this one though because it has the differential dial for the flaps - good idea.

Thanks to everyone!
