If you're really lucky you might be able to find a pair of Paradigm Studio 20s here, on eBay, Craigslist (much less likely), etc. They can occasionally fall through the cracks for less (I got embarrassingly lucky w/ eBay a number of years back) and are pretty spectacular for that price. I also think both the PSBs or VSs would be a really good find if you can find 'em at your price point. That part's all a crap shoot, and you may have to lurk for a while until you find a decent deal at your price.
Budget minded bookshelves
I'm beginning to build my budget college setup (I'm a freshmen) and am really confused when it comes to speakers because there's just so many choices. I already have an Onix SP3 MKII integrated amp and a Fubar II USB DAC. Right now I'm looking for some decent bookshelf speakers in the $3-350 range used. That price does not include shipping. Any ideas? I'm looking at mainly B&W DM602s and PSB B25s. Since I'm around 150 miles from any kind of dealer auditioning isn't an option -- but I'm okay with buying and trying, and selling if necessary. None of the dealers I can find have any "low-end" stuff in stock.
