I just did 6 rolls of 120 at TIW a couple of weeks ago and it was amazing. I took them in at 11:00am and picked it up at 3:00. Four of the rolls were E-6 and they came out amazing. I will be mailing my film to them more often as it was a bit of a pain to get into the city etc. I live in Waterloo and the only e-6 processing in town is $14 per roll versus $6 per roll at TIW.
Cheers,
Sean
