I need an enlarger timer -- something in the $25 - $50 range. I had been holding out for a digital one, but maybe I'm being fussy. I had gotten a Paterson digital timer, but the buttons were bad (contacts worn), and I returned it. I see the (analog) Gralab 300 come up a lot. Are these things the workhorses they look to be? I want something that's realtively easy to set and that will last for a while. I don't think I need anything too advanced; I don't print that frequently. Thoughts?
