I have a pair of the Lezyne Power Bottle Cages on 1 bike for less than a year. Easy to use, strong, super tight grip.

I've also got Blackburn Mountain Bottle Cages on a few bikes, including my LHT. They're the standard design, also easy to use and strong, with a tight grip (not as tight as the Lezyne though). The price is right on the Blackburns at 5 bucks a pop.

One bike has Ciussi aluminum cages. They also work fine.

I've had absolutely no issues with these aluminum cages marking up my bottles, probably owing to whatever it is they're coated with. The only aluminum cages I have, that do this, are a pair of 30 year old Specialized cages.
