Landice treadmill. Check your local craigslist for the best deal as they are really really expensive brand new...the difference in price could be thousands of dollars. It supports up to 500 lbs for the newer models and 400 lbs for the older models. As an owner of a very expensive full home gym, I would NEVER buy all that equipment again!
A good quality treadmill, some free weights is all you need...really! These will get you better results than all the "equipment" in the world!
