This is fairly new, so I don't think a lot of folks are even aware of it yet, but Crownhill has a new board that supports Arduino shield add-on boards, includes a very nice, and 'free', PIC compiler for the PIC18F25K20 that works with this PIC whether you have thier board or not. http://www.myamicus.co.uk/ It's one heck of a deal for free.
