Ditto, Cycleops. Solid basic trainer. They come up often used because most folks lose interest quickly. Or a tiny handful get really serious and want a full zoot smart trainer.
I've had a Cycleops for a year, from a friend who'd had it in his garage for years. Works great. Really helped last year when I was recovering from injuries and illness. By the time I was able to get back on the road I still had about 75% fitness. I still use it once or twice a week to loosen up the legs before a workout ride outdoors, or for short interval sessions.
