I have the Bontrager Race Lite cages. They look really cool for not being carbon. They were only $10 a piece I believe. They are 38 grams and are sturdy. I bought a $50 carbon cage from Planet Bike and it broke after a year of use but these Bontrager ones don't look like they'll break any time soon. Most importantly, I don't know one person who has lost a bottle with these.
