I got an email from Jonah@Partsbuilt.com and you should contact him if you are interested in the new board, this is what he said. If people from the forums can email me, I will get them on the list for beta testing the boards. I don't want to make the product page for it live just yet, since it will confuse other customers. I am just doing 5 boards at first and will be selling at a discount since they will have the PCB with the cut trace on the bottom. This is the board I now have on two machines and am very happy with. Jonah had sent me a screen grab of the temperature regulation without having to use the modified downtown board and it looked good. I am using the modified downtown board on my machines and get better regulation than my R2 had. The differences really do not matter because all are good enough for any practical reason.
