New verse old I always look at the condition of the old and remind myself of the warranty of the new. The X-ONE i uses a new integrated drive system made by Parker.This unit should come in as a promo model finding yourself under $8K. That along with financing that has been available makes buying a used unit tough. But spending $8K on a new machine may not be real easy for all. Look at the shape of the used piece and the price and weigh out the two. There are times buying used makes sense and there are times you need to walk away.
