Yeah, I've got one of those. What a price, I paid about $400 used for it and I've used it less than a dozen times. Plus the damn thing can barely be used with Konica infrared. I had to make a metal darkslide for it as the plastic one was IR permeable and the seals leak IR pretty bad too. The IR film was the main reason I bought it too. GRRRR.
I also had to cut a film holder for my Beseler from a smaller size.
As for panoramas its easier to shoot 4x5 full frame and crop.
One of these days I'll find something really good to use it for.
