One thing that kind of bothers me about every A vs. B thread is that a lot of people respond C, D, E, or Z. Given that the OP has a 16 game collection with some pretty high end games (including BBB) I doubt if the money is an issue. Any modern Stern vs. an early SS pin is going to be an apples to oranges comparison. I have a Kiss prem (which I really enjoy) but would love to have a Fathom. I would agree that a nice Fathom is hard to find so if he has a lead on a good deal the OP might be best to get it. His collection is mostly DMD games so a Fathom might be a good way to bring some variety into the collection.
