Jim,
There is a supermarket, Micheal's Fresh Market in Naperville/Aurora, that sells all kinds of stuff. They carry lots of things that the asian and hispanic communities use in cooking.
I talked to the butcher today and he gets in fresh meat twice a week and can get me anything I want. They do however always have fresh pork bellies, but I had to ask to get it by the slab instead of one inch stips. I was very impressed. They have the largest briskets I've ever seen, and two varities of fresh hams in at all times (boneless skinless, and bone-in with skin). Best of all I can place an order for hog jowels so I can make jowel bacon! I've been looking all over to find someone who could hook me up with this stuff.
It was a very good day for me and I was very pleased with this supermarket and it even got better once I finally got into contact with the buthcer.
I don't know if that will help you out, but I'd look around for any store that sells a lot of the interesting things that come from pigs (snouts, ears, intestines, stomaches, etc) and ask the person who does the ordering if they can get it for you. Asking the guy behind the counter is little to no good becuase all they do is walk back and look at the list of things in stock and come back and say no. The butcher I talked to was very helpful and brought out several cuts of meat to show me what they had to offer and what to ask for next time I came in. I wish I got that kind of service everywhere I went.
EDIT IN THE PRICE! I payed a $1.99 per pound for the fresh bellies. That sure beats $6 a pound for store bought bacon that is saltier and not as tasty as my own bacon.
I hope this helps,
Josh
