I bought these new 5 or 6 years ago for a bit more than $550 from Analytical Scientific in San Antonio and have been very happy with the views they've provided. Only reason for sale is (of course) to raise money for yet another gadget - this time it's encoders for the digital setting circles I just bought on Astromart.
Specifics: BAK-4 prisms, multicoated optics, 3.5 degree field of view, rubber armor, pinpoint stars with no "sea gulls" at the edges, Saturn's rings clearly apparent, minimal false colors, tripod adapter, case, and original box. They are fairly heavy. You will need a tripod or some other support if you want to look through these for more than about 2 minutes, but most any sturdy one will do. I have used these a good deal, but they are built like a tank and I'd say they are still in "like new" condition. No scratches on the armor or optics.
Price is $350 or best offer shipped to your door in CONUS. Money order acceptable, or I will be set up to accept payment via Paypal within the next few days.
Thanks for looking!
