Used Bookshelf up to $3k

@troutbum , A 3 way bookshelf speaker would qualify as something different. Since they make up a small percentage of that market, it would significantly narrow your potential search options down (compared to the available 3 way stand mounted speakers).

I'd go along with those recommending Fritz; you should be able to get a new pair for around that much, but used can be even better as those things can take a long time to break in.... 

From personal experience I would recommend to give Fritz a try as well. Very fluid & engaging midrange & vocals. 

Lots of good speakers out there though. 

ProAc 1SC.  I also like the small Spendors.
