Exercise Machine Elliptical

I would like to bring my little "TV while watching TV on my DVR. What would you recommend for a small space - treadmill, boating, elliptical machine, etc? Specific patterns and rates are appreciated. Ellipticals. Is my absolute favorite cardio exercise could be in it for hours and is very quiet (depending on the type of machine you buy) and is easy on the knees, burn more calories, because no one is economic and not necessary, to place on any part aha days. years can start with very little. running, weights, abs, and so far machinces generation has become, do not say bad, but wayyyy aha many unnessary. I think it's much more fun to run out and only or more with a sensation of running on the pavement as hard as a treadmill or us, and iPod in hand when external causes you sh.less bored.
