Please see the main VFET project thread for kit information. They will be available late June, at around $200.
In regards to PCBs, I have updated the registration of interest form so you can now state that you are only interested in a set of PCBs, and not in the kit itself. We have a few spare PCB sets so first in best dressed. If you've already registered your interest, click on the confirmation link you were sent and update your preferences (as shown below).
