Why are you so bent on the Saunders 670 DXL? I have recently set up my own darkroom and in the many many months of searching craigslist and forums like this, I dont believe I ever saw one avil. In the States, that model wont come up much in a community much for sale, generally you will see many more Omegas and Beselers than Saunders 670 DXLs.
