Fitness Equipment

I have been looking for a fitness equipment --treadmill to be exact for past few weeks and until now i haven't found any good deals. I browse kinda every where including our local forums and see if there's anybody who are trying to sell theirs. Well, there are a lot of them however, they are not what i'm looking for. I am not looking for expensive and gaudy looking equipment. I just want something simple that will last for years. My budget is under 100bucks, is it impossible to find one?
