Scott, it sounds like a nice piece of equipment, but it is
doubtful it will hold up long around a coil of the type you are
envisioning. Solid state controls/monitors and spark excited tank
circuits don't mix real well. I have lost lots of stuff; hand
held calculators, digital watches, and digital meters. I have
tried to keep the digital stuff near the coil cheap, and anything
expensive I unplug and/or remove to the next room when firing
high power Tesla coils.
