I also use a ZMII with an older, pre-existing Gralab, and love it - even though times need to be set manually. Because of the arrangement in my darkroom, I also manage the safelight manually. I chose the ZMII because of not knowing which direction I wanted to go in augmenting/upgrading/replacing my old Omega D2V. (As I recall, there are different models of the Analizer Pro for use with different enlarger types.)
