Just bought a spare Gralab 900 (the buzzer on mine does not work well) on Ebay for $29. It is in perfect shape but the user had taped some fluorescent material over some of the buttons so it looked rough but now looks mint. One of my better Ebay purchases.
My wife is getting exasperated with me. Now I have a Gralab 900 (2), Jobo Process timer 8, Jobo Multitronic, Jobo Colorline 5000, Gralab 451, Gralab 300, and a Time-O-Lite. Now that I can measure it, all I need is time itself.
