Best Speakers under USD 2,000 Second Hand Price

Could anyone give an idea, about which speakers is the best for my budget under USD 2,000? for second hand price/used goods.

Thank you.
Based on room size, low-power amplification, and budget, I can chime in with a recommendation for a pair of older Altec Model 19s, though they are quite large themselves. I have never heard Audiokinesis' speakers but I have great respect for the mfr's understanding of what makes speakers sound good, so I think that might be a good avenue to pursue as well.
These Urei 813's.

Not mine, but I wish they were.
