I got these generic speakers (Black, Bright Blue LED perfect for you theme) from **** smith electronics for about $50 dollars Australian, there only 2.1, but still quite good.
when i bought my logitech z-3 2.1 speakers, they were replacing a creative 5.1 set that i got for the same price. just being 5.1 speaker does NOT mean they are better quality.
same here, cept im black/silver with blue CCFL's. i have the 4.1 Creative's...there only liek $60 or under now i think. Pretty nice for gaming and watching DVD's and stuff IMO.
I have creative 5.1. They are nice and all, but unless you can really take advantage of some bumping bass and get your rear speakers to work (unlike me) they aren't of great use.
I forgot how much they were, but it was between $60 and $120 USD.
