If my budget had allowed, I would have purchased the CPA2 instead, because I anticipate processing 100 rolls per month. I figured I would at least have the benefits of rotary processing and temperature control, and could convert to stainless steel later. The CPE2 is a bit small for commercial work, but still much easier and more consistent than hand processing. However, those plastic reels Jobo sells for the 1500 series tanks are worse than worthless. Maybe you can use those reels.
Some people love plastic reels and some people hate 'em.
I'm from the old school. I hate plastic reels. Always have and probably always will. I have had few problems loading 35 mm film onto the plastic reels, but 120 film has been disastrous. After ruining some negatives of Halfdome covered in snow, I decided to invest in the stainless steel.
