Wow! your wife is truly understanding - I can only dream a NuArc exposure unit. Though, my wife said the garage is mine as long as she has the final say with the house decor. The next day I was framing a small section for a darkroom.
I too took Per's Pt/Pd workshop but it was one on one. He told me about the combo he did with Jim and as soon as an opportunity with Jim came up I signed up. I hope 2 days is enough.
