A photo-therm Model 14 bath is better than anything mentioned so far, and at ~$100 used is a far better value. Does circulation and tempering.
it dose say that it has a motor to circulate upto 20L of chemistry
seems pretty good to me
might use it in my jobo which seems pretty casual regarding maintaining temperatures ...
Actually almost the same, but not. Maniacs need to consider the coarser metric is less accurate in the human range.

Crazy or not, even 1 deg F is fairly easily detected with experience with chem baths... I handle a lot of chems and spent years doing so, and after measuring temp, I got the feel for them at the range of use...
One tip is that at 68 deg or 20deg C, is solutions feel truly tepid, neither hot nor cold... Even with the plastic bottles I use, if they are truly tepid feeling, they are right for black & white...
I still use a digital thermometer for final and process checking, but it always seems to work by hand also...
Place your palm or top of hand on vessel while measuring temp to get a feel for it... (If room or you is not too hot or cold...)
YMMV...

The ability to measure as precisely with C as with F is separate from how much they same they are.
Exactly 20 is always exactly 68. The math doesn't change.
(f − 32) °F × 5°C/9°F = (f − 32)/1.8 °C = c °C
The problem of coarseness is easily solved in my experience by decimal points on a good thermometer, just as Steve notes.
Still, I'm glad that a joke got to turn into a session of, "But actually..."
Still, don't care for C
and why are EU camera mounts threaded 3/8-16
