For $6.98 at PricePoint, the Neo Eon stainless steel cages seem like an unbeatable bargain. I don't actually have any experience using them, but they're in a box of stuff I'm saving for a bike buildup.

When on sale, the Elite Custom Race cages also have a good price to performance ratio. They hold onto all my bottles over the rough stuff.

Cheap aluminum cages seem to break or fail eventually, but they're also usually so cheap that's not a big deal.

I've seen bottles ejected from those lightweight Chinese carbon generic and counterfeit cages. I won't use these.
