bookshelf speaker choice

I am planning to upgrade my speakers, I thought I would ask for a few opinions.
Currently I use a B&K amp and I am considering either new NHT classic 3's, used paradigm studio 40's, or used Von Schweikert VR-1's. All 3 should be the similar in price range, which would you choose. I want something off the floor since it's a small house and couple of small children which creates a need for speakers that are not floor standing. These are meant for stereo listening and mains for my HT. Thanks for the input.
There is a pair of Selah RC3 ribbons for sale for $695. IMO this speaker is in a different (better) league altogether than the speakers mentioned. Also it is quite a bit larger and heavier. More like a stand mount monitor. I would buy them myself, But I already have to many speakers. They are very smooth sounding and complement solid state amps.
Thanks, I would love the usher's but I haven't seen any in my price range. I have basically been looking for stuff between 600 and 800 a pair. I can get new NHT's for this, but I know there are many others out there. Since new is just shy of used, sometimes I prefer to try to get a bargain on a higher end piece of equipment. Since most of my system I bought used, I guess you could say I almost prefer it. If I'm completely honest, most people spending the amounts I spend go straight to circuit city and best buy. I can't bring myself to do that knowing how much good used stuff is out there. Any other recommendations?
Focal JM Labs Cobalt 806S
" " " Chorus 707s
Both discontinued but worth searching out. I have Cobalt 806S and love them, i paid $600. used. The new V series has a new (cheaper) tweeter, and they are not even close!
After reading lots of good stuff about them here, I bought a pair of Green Mountain Audio Europa's on Audiogon. For the week I had them, I was very impressed, but they are a bit odd looking (cabinet made of a resin incorporating crushed marble), and when my wife saw the black cabinets on black metal stands, she declared, "Darth Vader has to go."

Out they went, to be replaced by Von Schweikert VR-1's, which are much more attractive in the conventional way. It's no big deal to me, since virtually all my critical listening is done via headphones, but I think those Europa's are a special sounding speaker in their price range ($500 - 600 on Audiogon.)
