Regarding home developing and associated cost, I see that caffenol was mentionned. I don't have the math handy, but it's not a cheap developer : it can't be replenished or reused (actually some people claim to do it) so you have to mix it everytime, and pure ascorbic acid is not that cheap.
It will depend where you live and if you can get it, but it was my impression that rodinal can't be beaten on that front, HC-110 being a close second. Let's say I shoot 35mm and have a single reel tank that only need 300ml of solution. If I only ever do rodinal 1:50, I can develop 80 rolls with one 500ml bottle. Right now in my town that's available for 12,90€ (damn, I'm sure I paid 14€ last year) so that's 0,16€ a roll ! Now, HC-110 dilution b (1:31) : 110 rolls for a 1000ml bottle, at 39,9€ that's still a fair 0,36€ a roll. While We're doing some math, replenished xtol would be 0,22€ a roll (for 70ml taken from the stock solution for each roll), 1:1 0,46€ per roll.
Fixer and stop : buy the cheapest you can find, they'll all work. Probably foma / arista.
I'm curious : when you shot a film everyday, what kind of work did you do ? if it was mostly "training" shots around the neighbordhood, places you could get back to anytime, using a digital camera is not a bad idea... work on your composition without worriyng about the cost by shooting any cheap digital camera in black&white mode, and when you find a scene with an angle you like, go back with your film camera at a time when the light is how you want it to be. I'm actually thinking of doing that more often.
