+ 1 on the Sportsman's Guide to see what it out there. then go and search for the better price. don't forget to consider shipping costs!
All I do is range shoot and only field shoot once in a while so the less expensive models suit me fine. Out of six scopes I bought through SG, one was inoperative when i got it. SG handled the RMA. I was certain I would have to go to the Manufacturer. but you never know. the remaining five work just fine are all six are on my 22's and surplus rifles, one is a PSL-54
can't offer a suggestion on the rings, but Gunnie's suggestions sounds valid.
