I have 2B's and they are fantastic speakers. I don't know of anywhere, even online, stocking them with a warranty. If you are willing to go used try out Audiogon.com. Should be able to snag a pair for $200-$250, maybe less. They aren't the bassiest of speakers though. One review claimed solid output to 50 hz, but I don't think that they go that low in my room. I have them crossed at 80hz on my receiver. The extension that they do have is tight, and they don't try to go lower than they are intended so there isn't any sloppy or loose bass. B25's are pretty much the same darn speaker with rounded front edges and they say the driver's been improved. To be honest I couldn't hear much if any difference between the two speakers.
The Bics might play a little lower (I'm sure they're very close) but the PSB's are the superior speaker IMO. Ray said that there was very little dampening in the Bics, my PSB's have at least 2" of dampening all around and still go pretty low for a bookshelf. Although for the price I still think the Bics sound great. You can get them for around $100-$115 a pair plus shipping online.
Like someone said, if you want deep bass you'll need a powered sub. You should be able to pick something up that can more than do the job in most rooms for under $250.
I'd also suggest Paradigm Titans, they are pretty punchy little guys for a reasonable price.
I am very biased with regards to PSB. I think that they make a fantastic product for the price and are one of the best buys going in just about any of the price categories they compete in.
