The Q2 is a good bow also, but not worth the extra $ over the fx as far as performance and shooting characteistics, IMHO. (I think they are around$600)
I don't know If I agree w/ Vic here

While the FX is the quicker & less expensive bow, it also the bow w/ more recoil, vibration, noise, & a stiffer draw. The FX also has a very short sight window which causes problems for some archers. the Q2 IMO is a much better mousetrap.
