I've always wondered... I see full mini-labs on ebay for next to nothing, something that would have cost $20-30k back in the film days being sold for < $1k.
Every time I see one of those adds come up, I'd say "if only I had the space", anyway it's a bit of an insane idea (buying a minilab for personal use), but I respect the desire to do so, and I've love to hear how you go with it. I'd be interested to know how much they cost to run, how much chemistry you need / throughput to make it efficient, and what the heck you do if something breaks!?
