I have a Simmons ProDiamond 4X "factory reconditioned" scope on one of my cartridge rifles. I bought it for about $20 a couple of years ago, from either Midway or Midsouth - can't remember which. Regular price is somewhere around $80. I really like it and it has held up well. Crisp and clear imagewith about 5" eye relief. For all practical purposes, 4X is just about right for deer out to 175 yards. I wish I had bought three or four when they were available.
