Put it this way, the Durst 1200 was made in their amateur equip division, not their industrial division, which made things regarded as a distinct step above. But one tends to work with whatever they find. I finally dismantled my reliable old Omega D, though I might reassemble it some day as a convenient teaching enlarger. I bought two Durst 138's - one in reasonably good shape, the other for parts, which I later refurbished with an 8x10 cold light. I'm making room now for a Durst 184 color 8x10 unit. My best enlarger I built from the ground up, cannibalizing and improvising all kinds of special gear to make it happen. It was a fun 3-year project, but not one I care to repeat at this point in life. In this subject, condition means a lot more than brand, along with whether or not you need special kinds of carriers etc. Adjust them properly and put a good lens on any of them - Durst, Omega, Saunders, Beseler, etc etc, and you will arrive.
