Von Schweikert VR2's can be found at around $1500 used; VR4 Gen I's can be found for ~$1200; and VR 3's can be found (though more rare) for ~$700 (or less). I have the VR3s and the only down-side is their bulk, but if you really want a speaker that doesn't require a sub, bulk is a given.
I think you also need to consider what you mean by "no sub". I personally have never been satisfied with a "sub-less" speaker system not capable of flat response to 25Hz or less. There are many others who are completely satisfied with ~35Hz response. I'm sure it depends on your taste in music, as well as the room you're placing them in. This is a question you need to answer for yourself though.
