Interesting thread. (I too missed the title that sparked the early comments)
I am considering a Combiplan tank. My local pusher... er...
dealer has a single tank available fairly cheap. (If I added up all the "cheap" things I've picked up over the years, I could get a new car :rolleyes
The thing is, I'm quite comfortable with tray processing, and find that developing by inspection is really helpful for fine-tuning development. I do risk the occasional scratched negative when I get overly ambitious or shuffle the negatives the wrong way. I'd be interested in rigging up a slosh tray, which might be the best of both worlds.
I'm thinking I will give the combi a try and see how things turn out. If worst comes to worst, I might be advertising a "nearly new" combiplan tank in the classifieds.
Cheers,
