Avoid the "My magnification is higher than yours" trap. You are looking for a good 4 power, 40 mm front lens, the brighter the better. A super high mag scope will have a smaller field of view (called "Where the BLEEP is the DEER?") and will not be as bright. Additional lenses inside the scope decrease light that actually makes it to your eye.
You CAN hit Wally World and by a cheap Chinese scope- or actually spend some money for quality glass. You will be glad you did. There are some used scopes that are still in good shape that come up on auctionarms.com frequently. I am partial to the Redfields, but Leupold makes great glass.
i DO shoot some very high mag scopes- on rifles that shoot varmints at 500 yards. For deer at 200, a 24 power scope is a self inflicted wound.
