As a further update to this thread...
Recently I was going through my stack of unread magazines (my backlog is often a few months) and found an article on used laser purchases in A&E (December 2014). Access Business Solutions (and Rob and Diane Bosworth, specifially) was mentioned multiple times, including the website, with quotes from Rob. Needless to say, I had to write the author (CC'd the editor of A&E) and let him know of the manner in which ABS has been fleecing their customers. The author has promised to investigate from his end, but I can not say what, if anything, will come of it. As I've said before, the best we can do is warn as many folk as possible so they are not scammed in the same manner. And yes, since this pattern of behavior has been repeated time and again over 8+ years, this is definitely a scam.
