    Digital vs Analogue Timers

    So,

    Obviously there will be greater precision with digital timers, but for a brand new starter like me, do I need such precision like 1/10 of a second at this stage?
    I'm going to run with both hands...

    You may not need that precision, but assuming you're looking at used ones, the timing circuits in many electronic analogue timers use capacitors that degrade over time (decades). I had one here that no matter where it was set timed for about a half second. Even "new old stock" stuff could have the problem, as it's related to more to age than use.

    My Analog timers go down to 1/10th of a second so get what you can at a decent price. That precision is useful for print flashing (an advanced technique).

    It depends. For 1 second exposure, it's a 10% error rate. But for a minute exposure, it's not a big deal. IMHO.

    My opinion:
    1/10 of a second would only matter for exposures which were very short - and I never do super short exposures. My minimum enlarging exposure tends to be about 15 seconds, if it gets much shorter than that, I stop down the lens. With a 15 second exposure, +/- 1s is barely noticeable (the difference between 14 and 15 seconds on the exposure is about 1/4 stop) so precision is not the reason to go digital.

    I've used both, and happen to prefer the analog timers since I have a better feel for the amount of time when looking at a dial vs a display, but I currently use a digital timer, since it is integrated into my enlarger head.

    Get a digital timer. My previous Kaiser analogue timer was precise enough but it's repeatibilty was horrid.

    Analog (like a gralab 300) could be more reliable as the keypads for setting the digital timers get corroded over time unless you find one with a waterproof keypad.

    Digital could be slightly more convenient and repeatable (like if you have to make a whole bunch of consecutive 10 second prints) for short exposures.

    Probably OT but I have an old red Kodak clockworks timer. Messing around with it yesterday I got it to where it was just 15 seconds slow over 3 hours. And I think I can tighten that up a bit more.

    Digital timers work well with f-stop printing - I recommend them.
