I've shot 120 for a while and am only now getting ready to process my own at home. I dropped in a couple of rolls to a photo place here for processing (incl. pulling 1 stop) and got charged $24 per roll - $14 normal processing and $10 to pull. How much do you/have you paid? This is in Australia, but the amount is about the same as USD.
Just need to figure out how to put the extra rollers on my Jobo and no more expensive processing for me.
