Lyn's EM7 and Wolfmark's WM1 would be similar.
How should I go about purchasing EM7? Where shoul I look? And is it a good,well regarded board? What are it's differences when compared with Alice?
Slight differences in the layout and a bit of the case, just look up some photos to compare them. The Alice was inspired by the EM7. It's a well regarded board.
You will have to look in the aftermarket, so Classifieds here, mechmarket on Reddit, etc.
