Please add me to the preorder list if still possible. I've been mulling it over all weekend and I think the Sentinel is the supergun that will best meet my needs!
@arcadeprojectsrocks This supergun has already happened. On the first page there are files you can download to have the pcb made for you and a list of components needed. Some members on arcade projects sell some that are pre-made.
@arcadeprojectsrocks If nobody answers you I would go through this thread and see if you find post of people that are selling some and pm them. Iam sure somebody can help you out.
