The Octane Q37e is definitely a really excellent machine - great build, wonderful displays, very good exercise motion.

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 very annoying and noisy. Make sure you clean up sweat 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. Keep a towel close also to help clean up during and after use...
