Thanks everybody. I have been surfing the web (and ebay) and think I like the idea of a separate wheel/cassette rig. I hunted in my shed and actually found some good "heavy" super sturdy road tires. PERFECT for the trainer. I keep thinking about all those "extra" sets of wheels I had when I upgraded. Wish I had one now! I'm gonna check with my local LBS and see if they have a beater wheel then can let go.
