As a Merlin owner, I think the best contribution I can make to this thread is to give you the e-mail address of the manufacturer, Bobby Palkovic. He can be reached at KVESCHMIDT@aol.com. Bobby is exceptionally good to work with, and I know he'll be able to quickly and comprehensively answer all your questions.
P.S.--I am a very satisfied VSM-MM owner.
