Hi Dave
We have a kit or pcb option to be available soon on our ebay store.
I have the PCB for JBOT tested and also some good matching 2n2218 transistors that seem to be working okay.
Until we list the kit, you can send me an email requesting the pcb or kit.
The pcb is ready but for kit waiting for some components.
my email is vu3sua@gmail.com
