Hi, I used to do colour C41 at home with the CPA JoBo and the old Kodak varicolour chemical kits. Once Kodak stopped selling them, there was no cost effective alternatives down under. On the rare occasions when I shoot colour the local lab will process a roll for $2.50, nil prints. As Harold said, time and temp are critical and no where near as forgiving as B&W processing. If you're only shoooting 35mm IMHO it's not worth the effort, cheers Andrew.
