If you're not developing your own color film, give it a try. The basic C-41 or E-6 kit is about 20 USD. You can use a standard thermometer and tank available at Freestyle. I recommend E-6 to start with, because believe me, the first time you take a roll of slide film off the reel and look at all those tiny, beautiful little images... you'll feel magic. That's the only way to describe it.
