I'm looking at buying a spotting scope. I don't want to spend too much. I know, you get what you pay for, but it'll probably get most of it's use at the range. I'm looking at the Burris Landmark 15-45 x 60. Midway has one for $160 and that includes a tabletop tripod and hard case. My question to everybody is: Do any of you have one or ever used one and are they any good.
