The Patao is used by professional teams, such as here on Landis' bike. It really holds bottles securely.
I got mine from this Hong Kong ebay supplier for $40 each (Patao's retail for $ 90).

+1 for Patao's I have them on my bike, they allow for some height adjustment at the bolts. They hold well too and are easy to transfer the bottle in and out. I had the Tacx Taos like yours and got rid of them after about a year. They seem too thin and flex quite a bit, also the plastic around the mounting bolt snapped on one. Just dont seem that well made, more of a pretty thing.
