For Medium Format Film, Acros 100 is 2.69 / roll from Adorama. Ultrafine xTreme 400 is 26.90 / 10 pack on Amazon. Both are good films and I have a few hundred rolls of each in my fridge. I also shoot TMAX 400 typically pushed and I love me some Delta 3200 at 1600 or 3200 which is 5.29 per roll at Adorama right now.

For developers, I prefer TMax RS Replenished which will do something like 60 + rolls for $13 and Rodinal for stand development, a 500ml bottle will do something like 70-80 rolls. You can skip stop bath and just use water, heck I do just because the faucet is easier to deal with than stop bath. For Delta 3200, you might want something else, I use XTOL.

D76 is a standard which can't be beat and there is A LOT of information out there about it.
