I'll be retiring in the next year or two. Color film processing, particularly E-6, is getting hard to find locally as minilabs go out of business. Presumably their old equipment is up for sale somewhere. I'm wondering if it would be a practical part-time business for my retirement. Are these machines a hassle to maintain? How do you handle the disposal of used chemical? I wouldn't have to make a lot of money but I also wouldn't want it to tie me down 5 or 6 days a week. I think I'd like to run it maybe three days in a row and offer a week turn-around time and cater to advanced amateurs. Any thoughts?
