Alright, I just wanted to say thanks for the help everyone. I ended up getting the Z-5300e's (they're Z-5300's with a silver coating instead of black). Sure, they're not the BEST, but they're almost 10x more powerful than the ones I had and I got them brand new from newegg with free shipping for 149,99 - and I have a form for a $50 rebate, bringing the price down to $99. It was a good deal.
I'm sure looking forward to having speakers for my computer again!
