Please don't take offense, but you are making a CLASSIC rookie mistake. You are shopping for a fixed budget, which isn't a problem, but looking for new with high magnification, but don't really have an intended purpose spec'd or a caliber, etc. I have purchased both SWFA HD 5-20 and Bushy DMR 3.5-21 glass used in the equipment exchange here used for $800 years ago and champion them to the world in that price range.
