z-5300e are nice speakers.
paired with a good sound card though.
when i hooked them up to my laptop, it was no good.
The upper and mid range are nice, bass is sometimes overdone.
but it was well worth the $160 paid on new egg and for the THX certification.
I don't really think the cheaper 5.1 are worth it.
I heard them, the bass doesn't really sound quite right and some of the sounds are wierd.
So Id say, if youre really on a tight budget, get the more expensive 2.1 speakers if you can.
