Hi Brendan,
What is your budget?
If you are not in a hurry right now, you can wait for the T9x, that should be available by the end of the week (well, at the soonest!)!
Like the Hxt9x, but comes with DSM2 module (Spektrum) and is ready to be flashed to Open9x and the like (so that gives you maybe what is one of the best radio around for a low price).
You also have the new FrSky 12D... That should be available really soon (compatible with FAAST, Futaba).
But that's budget stuff (Can't wait to see the Frsky one.. Apparently comes in 6, 8 and 12chanels, and 16ch as it seems that you will be able to link 2x 8ch receivers!).
Second option, might be to buy a second hand good radio, and then convert to 2.4ghz (lots of choice for conversion, Assan, Frsky, Turnigy, Jeti, Multiplex etc etc)
