I haven't read through the whole thread, so forgive me if this had already been mentioned. While it seems you're already steering away from Vermeer, something else to consider is their reputation for popping tracks off. This happened when we demoed one a few years ago, and then I heard that it was common for vermeers.
We eventually went with the DW Zahn, but I prefer the SK models myself. The crew I'm with now had to rent one while our mini was down, and the controls were as dreamy as I remembered. Super smooth and intuitive. Between Boxer, Vermeer, Ramrod, and DW controls and overall performance, I feel that DW outperforms the rest and at a competitive price.
