I will say that the optical switches are just freaking amazingly accurate. And IH's are beautifully made.
pzzamakr please note I said I didn't know if the statement was correct, but that I would find out. Sounds like you already have. I am curious about the IH switches. I am trying to build my switches now because I couldn't find the IH switches. Are they still available? I looked on their site again last night and could not find them listed???
