I own a Cycleops Fluid2 trainer.

I have really considered getting rollers to work on the balance component you get from that.

I would LOVE to have a Spinning bike. *sigh* I don't think I have been 'good' enough for Santa to bring it though...

Just additional info if you don't know this already...

Rear wheel trainers are notorious for eating up tires. Lots of folks save old tires with a bit of life left in them to switch out for inside. FWIW.
