Honesty is where this thread stops IMHO. If the seller advertised the machine had a 'new' display then there are issues. As long as the seller is honest and describes the DMD as fully working and not brand new then caveat emptor. The replacement DMD could last years to come, it could last 2 weeks. Who knows but as long as it is described this way then it is all hunky dory as far as I am concerned.
