I want a 200x, but had to settle for something I can afford. It is a 2000 yard RF that claims effective range to 1000 on non reflective targets. I think it will be just what I want. So far, I have decided that unless it has a 2000-2500 yard max range, it won't work at 1000 in real life. I picked mine up on eBay for $300, so I hope it's a good deal. Hope to hear some good reviews on glass and operation.
