I just got a Blackburn magnetic one for my dorm room. Its kinda loud, but not bad. My roommates don't complain. It has six different resistance settings. Also, it was $20 bucks cheaper at the LBS than say, Olympia Sports etc. So, i got it for $188, and I'm impressed with it. Only thing that sucks about it is not going anywhere (of course

), and trying to stay motivated to ride it. I usually turn the tv on loud or bump some tunes to keep me going.
Furthermore, use a crappy tire. The roller will start to eat your tires pretty quickly if you don't have the correct pressure on the roller/tire.
Hope this helped!
