I spoke with Jeremy over at GN for a few days consistently. He was promt about responding to my messages and answered all of my questions. He worked out a great price for me when I seemed hesitant of making a purchase. Thanks to him, I'm sure GN has a customer for life now. I spent more than I had originally intended to, but I went ahead and purchased the MS0006 model. It wasn't too much more than the 4 model, and I'm sure I would have kicked myself in the butt later for not spending the extra for an upgrade.
