The Octane Q37e is definitely a really excellent machine - very ruggedly build, wonderful displays, very good exercise motion, all with a fairly small footprint.

Be very cautious of one thing though: Cleaning the wheels. Everybody emphasizes how quiet the Q37e is, but if you don't clean its wheels very diligently, it'll rapidly become annoyingly noisy. If you're a big-time sweater like me, you want to clean it after every use. Also wear a T-shirt while you exercise, to soak up your sweat and thereby reduce the amount that gets onto the tracks. In my case, since I'd drop sweat all over it...
