This is a fantastic kit! I gave it to my brother-in-law for Christmas and he and I are currently building it. We're about halfway through and we're having a blast. The instructions are really well written and clear and the quality of the PCB, Nixie tubes, and other parts are top-notch. And the design is really clever and clean. But the thing that really makes this a next-level situation is the customer support. We've reached out a couple of times via chat and email and Pete has been immediate and crystal clear in his responses. I recommend going with PV Electronics without reservation; they've earned the highest rating I've ever given ANYTHING online!
(I'll update this review when we complete the project).
