I've been doing it for about 2-3 years. I don't print all my color photos myself, though; for small prints, it's usually cheaper and requires
much less effort to scan the negatives (which I do anyhow) and have them printed digitally from the scans at the local Walgreens. If I put the effort into it (or get lucky), I can usually get better results in my darkroom than I can from scanning and printing digitally; I find that scanning tends to exaggerate the grain, which can be objectionable with films faster than ISO 200.
Unlike some others who've posted to your thread, I use open trays -- the same ones I use for B&W. I've tried drum processing, but I find that it slows me down, since it takes so long to dry the drum adequately. If the drum isn't dry, it tends to drop water on the print, which causes greenish streaks. I don't mind working in total darkness for a couple of minutes, which is what it takes to expose and develop in room-temperature (RT) chemistry. Others have other preferences, of course; this is a personal preference matter. Using "regular" chemistry at RT requires longer processing times, which gets a little disconcerting for me, so I stick to the RT stuff. (I use a
mix-it-yourself formula of which Photo Engineer does not approve, but I'm satisfied with the results. YMMV.) Of course, a processing machine would be really nice, but the last time I checked, they were a bit more than I could justify spending, even used on eBay. Maybe one day I'll spring for one, but for the moment trays work fine for me.
