Take a serious look at the Minoura rim drive trainers. I sell them at my shop and ALL of my customers love not burning through tires. There are a few different types as with all manufactureres but well worth the cash. I spun on the one that I use for fittings during monday night football and the thing just hummed quietly. That is the RD-850. I've found that the remote switcher isn't really needed since you can reach the tension adjustment with your foot if you snap out of your pedal. Here is a link to the site:
