ok ok, if you really want advice from a guy who doesn't use one much, here's what I know.
Cheap ones seem to mangle quick releases. Buy a cheap qr and use when you're on your trainer.
The new roller style with the sliding mechanism looks ideal to me, more movement, more interest factor, but they don't fold, and weigh a lot. (Mike Lawless has one. But I think it's dirty, so maybe ask if he wants to sell it.

) Maybe wait a year or so until the lighter folding models come out?

There's a middle step, the kinetic.

Get resistance adjustment you can reach from the bike.
Look for plastic parts that might break, and avoid them. I have one like that.

How you set the tire tension affects tire wear dramatically. I wore a tire out this winter in about an hour and half by not having it pushing hard enough on the roller. Left a lot of rubber on Eric Simonson's classroom floor. Looked like i was riding in a circle of black dust. Trainer tires are available. I'd buy one. Maybe a wheel just for the trainer so the qr thing is ok too?
Have a sweat management plan. I have a donated frame with a big rusty patch where the previous owner dripped on it. And alu can corrode too, it's not just steel. Dunno what carbon fibre does, but you're not in immediate danger of that are u?
Others?
