Hello Crispy,
I going to be using the FlySky FS-T6 2.4Ghz digitial 6 channel.

Picked one up for under $100 delivered, but you can get them for as little as $70 if you are willing to wait on international snail mail.
I also considered the Turnigy 9XR for around $60 US (excluding shipping), this doesn't include the separate RF module. All up including shipping would be around $120, or cheaper yet on ebay via international snail mail from China.

The 9 channel would be better for FPV with 2 or 3 axis gimballed camera and I should have considered that, but for these prices if the 6 channel is insufficient, I will get a 9 channel for under $100 if need be.
This is the kit I have purchased for the quad, bit of DIY in front on me in the next month. This was $124.78 US

In Aussie dollars the radio and kit set me back $297.62 which is pretty good I think. If I already had a suitable radio I would have got away with around a $200 outlay for just the kit.
This is a link to the kit for anyone interested. Please note, this is a Chinese knockoff of Crispy's DJI Flamewheel which is an excellent quad.
F450 Flamewheel kitThere are cheaper 6 channel radios on the market, but unless they are digitally proportional, I wouldn't consider buying them myself.
