...You didn't by any chance take them in the shower with you did you?...
I personally (the cheapest, that have done me well) like the Creative Inspire set (I have the 2.1 set myself, that I picked up really cheap).
Theres Logitech also, which produce excellent speakers (ones to go for, for a very very decent set), but they tend to be a tad bit more expensive.
With the Creative Inspire range, you get 2 standard speakers, and a subwoofer capable of 45hz to 20,000hz (pretty good), which will power a good sound card fine.
I'd say go for them because they are very low priced, but offer great sound quality for the price.
