Thank you so much for the great information you all provided. I decided to go with the consensus and while it is a bit on the high side, selecting the MC-30a seems to be the best solution considering its reliability. I spent nearly 10 years, practically the whole of my 20s in darkrooms. In some I was wearing a uniform, in others I was part of the free enterprise system. Had a very long hiatus from photography and I am still learning the digtital world both when it comes to the new generations of cameras and the Lightroom that replaced my beloved darkroom. Thank you again for your suggestions.
