Agreed on the ebay carbon cages, they are a tremendous value.
I picked these up last year for $24 shipped to my door.


Strong, light, affordable. And they look damn good on the bike(which lets face it, is why we buy them) I cant think of any reason why you would need to spend more. I haven't had a single ejected bottle, if anything they are a little "too" tight. Just a great value.
