Anyone have some suggestions for computer speakers? Looking to keep it under $100, preferably ~$50. Just looking for a 2.0 setup (with on-board amp) for office use. Perhaps it won't matter what I get at the low levels I will be listening at, but I'd like something that at least sounds decent. These will be an online purchase through Amazon most likely b/c of a gift certificate-so not really got get out there and worry about listening to computer speakers. Just wanting some opinions on what others have heard and liked.
