They are really intriguing, but not tempting enough to spend $300-800 per bike.
Self-install crank based Avios can be had for around $160 from various UK sellers. Avio states they only work with Shimano cranks, but with a bit of ingenuity I was able to mount one to my Campagnolo Potenza crank. It required disassembly of the Avio, and the application of heat to bend the case so that it followed the contour of the crank.
