I ran a QC2 for a while and it worked well for me...
there are some questions/potential issues with the BEC current available from the QC2 (which I believe they have adressed in the QC3)
I am currently running a Novak GTX and it works very nicely, although honestly I'm not a huge fan of Novak's constant desire to put buttons, lights, etc on almost all sides of their devies thereby limiting your installation options...
You may also want to consider the KO VFS-1 (Hara Twister) in your search...
$150AUD sounds a little on the high side for a QC2 right now though if you look at what they are going for on this board and others...and the uncertainty with the BEC current (possibly effecting signal with Spektrum and missing laps with a personal transponder) ....I'd keep looking...
