I was at Jerry's the other day, on 51st just east of Mingo, and he had a lot of different powders, except for the one I was looking for (HP38). He's a really nice guy, and his prices might be just a tad high but much lower than Dong's. He is just starting out and I'm going to try to support him as much as I can. It's good having someone down a little further south to go to for supplies.
