Wow, that would be quite the upgrade, I used a Fuji film processor, not sure if was the 232b, unlike printers the technology did not change much over the years. The lab I worked at had 2, we processed up to 1000 rolls a day, average was less than 500, towards the end as digital took over less than 20 a day. I live near a photo shop that still has a mini lab set up, they run their C42 processors 2 days a week and process around 30 rolls a week. I recommend that you use Hunt chemistry, my boss told me he tired another brand but had issues, don't recall what the problems he had. Ours were plumemed, I think it may be possible to use a bucket to collect wash water.
