Hello. I recently saw a gadget in the Porter's catalog (I get a lot of photo-related stuff in the mail) called a 'photo processor temperature control unit'. It's this sort of wand that you can submerse in water (or maybe developer?) and set the temperature from 65 to 105f. They say it's accurate to plus or minus half a degree. It's 120 bucks.
Can anyone tell me if they've ever used this thing?
Thanks much in advance.
