On many things like pickups and construction equipment, its often times cheaper buying it brand new, even excluding maintenance costs. The actual cost is the purchase minus the residual. Buying off brand crap because it's initial cost low is also a mistake people make. It actually costs you more because the residual is so bad on it. The opposite may be true for printers and other industrial equipment because the secondary market isn't real hot for it.
Zund brand cutters would seem to make the most sense buying brand new when you look at how expensive they are on the used market.
This feeds my curiosity some though because the machine that was traded was not old, wore out or really utilized. It seems like trading in your 16' flatbed truck because you might get a job with an 18'
sign.
