Re: spotting scopes.
Kowa makes fantastic scopes at moderate prices($500-$700) and at the high end. I think you need to be spending at least $500 to get into the range of scopes that are good quality, but I have seen one or two really cheap scopes that were pretty darned good. Of course, then their durability is suspect..had to have cut corners somewhere to get the price that low.
"clear image at 800 yards." Clear image of what? You actually don't need all that great a scope for highpower competitions. It's when you are hunting that a top scope is important.
