I have a Bushnell Excursion 20-80ED. I am very happy with it. I can resolve bullet holes in white paper @ 600 yards. I do wear glasses and think the eye relief is lacking a bit, but I got it very cheap at a store closing. The image at the far edges is also a bit blurry but doesn't hinder you at all with the 80mm OBJ. I have read others say the same about the blurry extreme edges and eye relief as well. I have no intention of sending it back for repair because I'm afraid it won't come back with the high quality imagery it currently has. In other words I think it's so good I'm afraid to mess with it. I haven't looked through anything else other than a BSA so my in put is very subjective.
