If I were in the market for a new spotting scope I would seriously check out the Pentax PF65ED. It is ED glass and has a great picture. It is fairly light and if you shop around you can sometimes pick it up for around $599. I would check with Doug at cameraland to see if maybe he has any demos or when he might get some in.

He is great to deal with and he will tell you straight up what he thinks.
