Meh. For the money, or 100 more you can get something way better. Midas Tac, Nikon FX-1000, Ares BTR, and Steiner PX4i, can all be had new around that price. None of them give up anything to to the 4200s I have owned. The ones I had were 2.5-10, great little hunting scopes with pretty good "glass." What was "good glass" 20 years ago, is run of the mill today. IMO.
When I auctioned them on Ebay, I was surprised what they brought. You always have to remember on auctions though. One may go for 610, and the next might go for 310.
