I have seen several in action, but I've never used one myself. I like the looks of their machines, they seem to be well made and accurate. I think the major reason for the variation in price is one, the quantity of these machines that are sold, and two, the larger the retailer, the more they have in stock(usually) and the better the price they can offer it at (usually). One thing I would look into before I purchased one of these is the setup time needed between operations. If I have to take alot apart and adjust alot of variables, then I am less likely to use the machine next time! Hope this helps!
