I have been looking at the Tacx I-magic trainer. Has anyone had any experience with these systems?

The Tacx CycleForce Flow Trainer announces the start of a new generation of Ergotrainers. Heart rate, power, speed, and pedalling frequency are measured and visualised on the modern display of the Flow computer. These training data provides an important instrument for targeting and improving physical fitness efficiently - resulting in optimum performance.

The Tacx i-Magic virtual reality bike trainer connects to a PC and operates via a USB interface on the handlebars. With the i-Magic you are able to produce your own programs, experience dynamic riding while feeling the resistance of the terrain and produce your own fitness test.
