I have a Montego and I am impressed in terms of cost/performance. It especially has very low noise and for hd recording it is therefore great. Forget about wave table synthesis though- it is crappy, like all other combination sound cards I've seen or heard. If you want good wts sounds get a Sound canvas (virtual or stand alone or even the old SCC1)
I have owned the AWE-32, AWE-64, tested the AWE-64 gold and Live, and my opinion is still that Sound Blaster is for gamers or for those musicians who only want to mess around.
