@RobertWhite - you know, I considered Bills and dismissed because it WOULD have to be a different item, but to be real, they really should have a different item number anyway, so you don't accidentally sell a used machine to a client as new. (And to @JeffSchwenk - the RMA should be 10K but then they need to add another 5K which may involved taking parts out of inventory to the item after it's already in stock.)
