He had a damn fine product at a good price. Materials cost (to customers trying to duplicate) was probably about 50% of his price. Engraving, wiring up the switches and (optional) cable was the rest of it. No wonder he was weeks behind! It wasn't anything any of us here couldn't have pieced together, but at the price he was asking for his ready to go kit, it was a no brainer to simply buy it. His documentation and even a supplied cut-out template was first rate, albeit rather oddly printed on 4x6 index cards! Mine dropped right in and worked correctly the first time because it was made right and documented correctly.
Goddess Bless him whatever his current circumstance is. I too hope he's OK...
