I have the Prorace Lightweight Cages on my bikes and they are great. Pretty much the cheapest around and also one of the lightest too (9 grams lighter than Tacx Tao). I had Tacx Tao on a bike I recently bought but my bottles (standard plastic ones) didn't seem to fit the cages properly and nearly fell out when I went over a bump so I took them off and replaced with the Prorace ones. They are only bottle cages...don't need to pay mega bucks for some fancy CF one, not going to effect performance in a race one bit.
