Well, Robert, you're making me feel good about spending the money for a Durst 138.

Beat you to it, did that 23 years ago! Had both a Type 1 & Type 2, hated them both. L
Fred et.al. designed the Type 1; Calumet designed the Type II to correct some deficiencies of the Type I after they purchased Zone VI.
One of the Type I deficiencies was that it didn't cover 5x7, even though Fred Picker sold it as such. Calumet's Zone VI lead told me that it was originally designed as a 4x5 enlarger with an oversized head.
My problem with the Type I, was that it did not have consistent contrast print to print, or especially, session to session. I suppose that the compensating timer would correct for overall exposure, but it couldn't correct for the fact that the green and blue lights could vary independently from each other. Calumet tried to fix this by installing a compensating circuit for each of the two colors. I could have resorted to split printing to solve this problem and exposed the two colors individually. But, I don't really care for split printing.
For me, long exposures was not a problem for the Type I. The control box was big and heavy, I believe because they contained heavy duty power sources. I had no problem enlarging 35mm negatives with my Type I. Calumet put much lighter power sources in the Type II head itself, and I believe this restricted the intensity of light that could be produced.
Anyway, I now use my Zone VI Type II with a Beseler 45s head using an adapter produced by Zone VI. The 45s head and the Zone VI chassis make a nice combination for what I need.
