Tough call, I see all sides. Remember that once dual pin ownership happens it gets serious.... You will have TWO machines to maintain. That being said having the variety is awesome. And really those are two rock solid machines IMHO as far as general reliability is concerned, I think most would agree on that. I've never played a STTNG, but I love the show. Will have to check one out some time. If there was any $ on top, even a little I would be very tempted. I personally think SYS 11 games rock, and want to make many a focus of my collection.
