I'll second the nod for PSB speakers. I own some original Alpha's and Century 300i's (both bookshelf speakers) and am currently running some T-45 towers. The 300's and T-45's I picked up used off ebay and craigslist at crazy good prices and consider them some of my best music-related purchases ever. I would get the T-55's or T-65's if I could do it over again since I want a bit more low end and the 6-1/2" drivers would probably sound a little fuller than the 5-1/4" drivers. Might pick up a sub and go the 2.1 route.
I also have some Athena AS-F2.1 towers, also picked up on craigslist, and they pale in comparison to the PSB's. The Athena's have almost zero mid-range compared to the other speakers. Even bought a more powerful receiver, HK-3490, because a review on Stereophile said they need a lot of power in order to sound good. I've held on to them since I'm curious how they would sound w/ a tube amp in case I ever man up and get one.
Here's a good site for PSB stuff:
