I'm definitely intrigued by the E-motion rollers, but that price? EEK!!!

Do you use your regular road tires on the rollers or would el cheapo tires or perhaps those Conti Hometrainer deals work better? I have a KK trainer that I use with Spinerval DVDs every now and then with a old beater bike with one of the Conti tires on the back wheel, but rollers sound like a good way to work on my pedal stroke and balance with my actual road bike. Hmmm....
