You know, I actually switched my slide development to my local supermarket who then mail it to Konica up in Maine. It takes 10 days but for non essential stuff, it's great and costs $3/$4 for 24/36 exp. I did a test with two rolls and the only justification to the pro lab for paying around $6 more was that I got it the same day versus 10 days. Your milage may vary of course.

It all depends on what you want, I suppose.
