GHI also produces a variety of .Net Micro Framework boards. I've used their Domino board before. It did what I needed and they provide pretty good documentation. http://www.ghielectronics.com/catalog/compare/[^] You might also want to check out this book if you haven't worked with the Micro Framework before. http://www.amazon.com/Expert-Micro-Framework-Experts-Voice/dp/1430223871/[^]
