- The CPE has fixed rotation speed. I think the older version has two
- speeds while the new version can do 70rpm only. That's way too fast
- for film processing. And as I recall, the CPE doesn't have a pump
- to circulate water between the upper and lower trough. That slows
- down temperature correction and creates local hot spots in the bath.

- Actually, the convenience of digital temperature setting is far more
- important than anything else. Dial in the processing temperature,
- throw in water a couple degrees below, go away for half an hour and
- you're all set. The cold water intake is also quite handy if you do
- b&w film in the summer.
