swarovski 25-40x75

[kicker]

I have a pair of swarovski 10x42el binos that you couldn't pry out of my cold dead hand, and i know a guy selling his s.scope. He say's it's a 25-40x75 and he wants $850.00 for it. Anybody with some knowledge of this particular glass have an opinion on it?

Thanks,
Kicker
