Small quibble - the pic on the page shows a 36-exp. package of Superia 400 - if that's even available anymore (I haven't seen any locally), the store-branded versions are usually 24-exp. anyway. The 24-exp. package is probably what's available for US$2.
That said, I agree with the audio blog that a big factor in the perceived quality of this film, or many consumer colour films, is the processing - if you can get clean and cheap c-41 processing locally, you're in luck. Since Costco pulled their minilab machines across Western Canada, I have yet to find local processing that's both cheap and good (eg, my negs don't come back scratched). I have since connected with someone locally for some repurposed minilab chems, and have started to process my own, which so far is working out just fine, but that may not be an option for everyone.
