I'd like to express my interest in a replacement for my well-loved Ilford 500H, which I use on a De Vere 504. I hope to get more out of the 500H, but I fear the day when it gives up on me might be sooner than later, and it would be great to have a replacement. I do not want to replace the De Vere 504, amazing build.

Ideally, I would prefer not to control the new head via an iDevice (which I own several of) but either a traditional timer, or a dedicated unit, letting me control grades in 0.1 increments. It would not need to be a StopClock style timer, just simple time and grade, focus, expose, burn, and a foot switch.
