again - creative never made a really pro card and i don't think i's their biz. ok they're cheap but soon you will look for replacement and on the end of the day the money you spend on 2 cards...
if you just want it as an interface for a sofware sequencer (in this case i suppose you own a midi synth) so no problem, but digital audio is the next step and you will want more quality.
Turtle Beach is a good option (maybe you still can find some tahitis on the stores), i heard that audiotrix xg is a good one (it uses yamaha chip). If you're on a budget consider something used.
