I got started devekoping my own film for under $200 and it is easy. Again, just takes practice. And it can be done in a downstairs half bath or a closet. Any space that can be made light tight.
...or even an area that is not quite light tight enough for film, if you use a changing tent. (Yes, tent, not bag. I have a bag because I got it for free, but it drives me crazy, especially when doing slightly more complicated things like trimming off a roll midway through or loading sheet film holders.) I have never really made any spot in my home to be light tight enough for film. Paper, yes, but not film. When processing at home, I always load in my bag (with the lights off).
You don't need a great darkroom (or even a good one) to do great work!
