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