I paid just under $300 for TX, RX and a few goodies from my LHS. But then I packaged up my 8U and ebay'ed it for something like $285 . So my upgrade was free - it only cost me a few "standard" servo's that I had no need for anyway.

I DO like the robustness of the 9Z "conditions". They are exactly as sfaust explains. But I'm not going to pay $700 more for that. That's just me. I'm super happy with the 9C

The idea of a 12 channel should appeal to the turbine guys. They eat up all the channel pretty quick.
