Is there any update on your testing of this unit? I am very interested in getting one. I have a new 12x20 camera and I need a vacuum frame and lightsource and this seems like the perfect unit. I have checked eBay for Nuarcs 26-1Ks and individual components but finding ones in good shape that the seller will ship has not been possible. It also seems that none on my side of the country ever show up for me to pick up locally. So, I'll look into buying a new one and this seems to be a perfect fit.
Please let me know how far you are from making your final assessment. Do you see any reason why I can't order one within the next month, after I pay uncle sam?
