I have a CT and a large diameter set of rollers at home. However, I travel by auto a lot in the winter months and want to bring a bike and, preferably, a collapsible stationary trainer or, in that alternative, a small diameter set of rollers. This would also serve to help me warm up at races. Cost is not really an issue, but I am cheap. I am really looking for a stripped down trainer that is relatively quite. Recommendations?
You have all the toys. 
If you care about power feedback, I would recommend the TacX Flow. I used this trainer for a couple of years prior to buying a CT. Good quality and easy to travel (by auto) with and easy setup/takedown…folds flat.
pot calling the kettle black : )

Shit, that is a CT replacement for me. I seldom use the 3D software anymore.
Hey! All my bikes are 8 years old or older, and I don’t even have a track/SS bike.
Well, the picture may not be worth much but the course variety I find helpful. As well, using the data w/ CyclingPeaks is great. I also use a front fork mount w/ my CT (not avail w/ Flow). IMO CT better for a more permanent setup. Love the TacX Flow though and would take it on vacation/long weekends all the time.
