I find that it makes a lot of sense (well, for me, anyway) to use separate timers for dry and wet processes. For the enlarger, I cast another vote for R.H. Designs. I use their Analyser Pro. The model I have is specifically designed for the Ilford 500 Multigrade head. When I first got it, all I could say was, "Wow!". I still do; it's great.

At the sink I really like the Zone VI compensating developing timer.
