Right now, I'm going to hold it at one. No matter how many PCBs you get.
I got a limited supply from pgrzelak, which he got from Noritake. (About.. 20 units.) Once first run of orders are gone, I'll let people order extra units seperately. (Maybe he'll sell 'em directly.)
So, for now, I'm limiting it to 1 VFD per person. As many PCB's as you want..

Thanks!
Me.
