I'll tell you what NOT to get, a Tasco Pro Point. I think it's discontinued. I have one on my .30-30 barrel which is compensated and doesn't recoil too bad and it's held up fine, but I had it on a .45 Colt barrel, really heavy recoil with hot hunting loads in the 1000 ft lb .44 mag category, and I shook the reticle loose and had to send it in for repair. It is a 30 mm scope and has a good field of view in 2x, has worked fine for me on the .30-30, but I wouldn't buy another one.
I wanted that variable 1.5-4x Bushnell for quite some time, read a lot of good stuff about it in the rags, but never got one. Burris or Leupold are probably the better choices, though.
I've got one other scope I picked up for 75 bucks, branded "Dan Wesson". I mounted it on my .22 barrel, so I can't say it's great. LOL But, I doubt it's in production anyway, either.
Mounts and rings, I heartily recommend Millett. They're all steel and very strong. Rings and mounts are important on a heavy recoiling gun and Milletts can handle it in my experience.
