I would still take a look at the SW1000XG. One just went for $180 on ebay. And IMNO it kicks the SB Audigy butt. Now if you want some REAL nice sounds go with a SB or any card that supports soundfonts. Then get AnotherGS and add the patch to make it AnotherXG (it's only 32mb) then add the sounds YOU like to it using the E-Mu Librarian, or Vienna. That is what I have done, and I am extremely happy with it. Just a thought.
PS-I us to have the SW1000XG and the Roland SCC1 both in the same system (p3 700, 512) and it was a nice selection of sounds that didn't eat the CPU for lunch.....
