    I only use my gralab 300 on my older 4x5 durst as exposures are long enough not to worry about variation of second timing. The gralab is not very accurate when setting exposures that are short. Same with time-o-lites, not very accurate. They are popular because they are simple and affordable but not the best choice if you have a little bit of a budget to spend. On my main lpl 670 i use a gralab 450 with footswitch. Very slim machine i have wall mounted behind the enlarger. Dials as i dont like the button time setting design versions of the more advanced gralabs. Dial setting is also very fast. Metronome when counting down, great for dodge & burning and 0.1 second timing, which is really needed for small prints with the head low.

    I never connect the timers to a safelight as i use a thomas duplex, i just dim the vanes if i know im going to be working for a bit of time with lots of paper out, such as cutting from long rolls. If it turns off it needs to warm up again before its safe to use.

    Failing that, a loudly ticking clock. I printed for my first year with a loud clock and a table on the wall listing 1/4 stop timing increments. I would take the ticking clock over a gralab any day.
    I've used RH Designs timers and they are great. I've also built my own using Polyglot's instructions. I do not want to go back to a plain timer. If I had to I would get a digital that I could use with a table of fstop times. Having the ability to program steps in is also very nice for complicated prints.

    This is my favorite timer, ever. I hope this thread doesn't drive the prices up!

    Use glow tape all around the perimeter of the switch, or mount on the wall, or both.

    The gralab foot switches are not that common and dont pop up much. You can get a brand new foot pedal online or a music store that has a 1/4 inch output, a mono 1/4inch to 3.5mm plug adapter and you have a fully functional foot switch that can do start stop on press or double press to use on your machine. Get whatever size or color you want costs under $15. Much easier than looking for a used switch online.
