I've got rings from $20 leupold rifleman rings, TPS TSR rings, to 34mm badgers, and I'd recommend a set of TPS rings, which fall right in that "mid-range."
This is just personal opinion, and I don't know if there's any science to back it up, but for repeated installations and removals, I'd spring for a set of steel rings. My set of TPS rings are fine for what I use them for, I would buy them again, and well worth the money, but the badgers just feel like they'll last forever and hold up better over repeated installation cycles. Like I said, I don't know if there's anything to substantiate my opinion, as it could just be the weight of steel compared to aluminum that makes me feel that way.
