Welcome to the forum JV. I would recommend a scope with a very good warrentee. I bought a Leupold varix II 3-9x40mm, for $179 at Academy sports. That model has been replaced by the vx 1. Truth is I put it on 4X, and shoot from there about 90% of the time. It is warrenteed forever no mater who owns it. Burris is another good brand. They might cost a little more than you wanted to pay, but they will never let you down. Both brands have high end scopes like $700. but this is way more scope than you need. I'd stay away from the real cheep scopes like BSA, BEC etc. Tasco has gone out of business, and so their warrentee. I don't know about simmons, or bushnell. I have heard good and bad. I've heard good things about weaver. I have a cheep 3-9x32 sportsview, but haven't used it much. I was afraid to put it on my mini.
You can get some good deals at pawn shops sometimes. Here are some links to shop around, some have better pictures, and info, and others have better pictures. You can't beat going to a gun shop, or gun show, but shop around before you buy, it could save you a lot of bucks.
The mini is known as a scope wrecker, so many of us have greatly reduced the recoil by installing smaller "gas bushings" or "gas port bushings". You can use the search button in your upper right control panel for more info on gas bushings, and scopes. Hope this helps ya get pointed in the right direction.
