You might consider either a Shapeoko 3
or an X-Carve
(which is really a slightly juiced up Shapeoko 2. The X-Carve currently has more expansion capabilities, Ed's dealing with keeping up with sales for the initial SO3 and (the last time I looked) hasn't had time to work on expansion packs.
Edward Ford designed the Shapeoko while working his day job, got hired by inventables and designed the SO2 (I think it was that order, maybe he did the SO2 then Inventables), left Inventables and designed the SO3. I've corresponded with Ed a number of times over the last few years, he's a good guy. When some more space opens up in the Mooseshop an expanded SO3 is pretty high on the list things to fill it with (although it'll have to duke it out with a CNC'd G0704...).
Not knocking PB's design, which looks pretty good, but PB seems to spread themselves a bit too thin, and I'd wonder what the future of the CNCand other non-3D printer products are. They're still having QA problems with their 3D printers and controllers, and there's been several customers "fired" lately because of too many tickets. While it's likely there's legitimate issues on both sides of that item that we'll never know, it does raise a flag. A new design CNC router has the potential for a lot of tickets...
