C-41 is quite easy to do and pretty short times you can do it in an open tank in the dark if you are dipping from one tank to another to avoid timing errors from prolonged pouring times. Only thing I don't like is the short life of the developer once mixed. Using it one shot if from concentrated you must be careful to exclude air from the developer concentrate or it will die on you before you get to use it. Happened to me. I now purge with nitrogen before closing the lid.
Biggest hassle is getting the solutions to temp and stable but a tub full of water once gotten to the right temp will hold it for long enough to do the job with no problem. A Jobo system solves this problem hands down but I don't have one myself and see no need for it personally.
