Used Kurt Kinetic road machine with Pro Flywheel upgrade. This thing is a rock and I've never had a single issue, just works every time. I upgraded the flywheel with the Pro add-on.

See below for description of the pro Flywheel from manufacturer:
Upgrade your Kinetic Road Machine or Rock and Roll trainer with the Pro Flywheel Accessory Add-on. The Pro Flywheel's 12lb of additional inertia increases your trainer's 'road feel' with longer accelerations and decelerations.
