I'm planning to buy my first MF camera next week (I'm leaning toward a Mamiya RB67 right now), and am wondering what is the best way to get the film developed. I'm hoping to be able to develop B&W film myself by September, but I would also like to shoot some E6 and C41, and I don't have any way to develop that myself. So how do you guys do it? Do places like WalMart take 220? B&H sells mailers, but they're $30. I don't need prints, just the film. EDIT: Should have put this in the Film Discussion forum, my bad. If someone wants to move it, please do.
