I've worn the Ixon one-piece (haven't seen more than one variation from them). Really good quality, feels bulletproof, would have been a better fit for a slightly shorter person than my 5'11", 76kg frame.
I'd actually buy one if it fitted me.
In the sub $1k range of sutis I would highly recommend Ixon, Shift, and have personally tested Quasi's gear at around 150km/h with very good results.
