That is basically true. Look, all exercise equipment sales people will have their preferences and try to push you towards the products they like. The best suggestion I can make to you is to go and try out some treads.Make sure you go to an exercise equipment specialty store where all the sell is exercise equipment. Do not go to Sears or a sporting goods store. Try out all the different brands. Pacemaster, Vision, SportsArt, Precor, Lifefitness, Trimeline. After you find one that YOU feel is comfortable for YOU to use come back on here and let us know what you found.
The most important thing about your traedmill is that you like it. It could be the best tread in the world but if your not comfortable on it you will never use it.
As for refurbished it can be a great deal but you just need to buy it from someone who does a good job of refurbishing it. There are only a few refurbishers I would trust.
Superdawgy - Like I said, we all have our favorites.
