Blue Star Cartridge & Brass
They do gun shows all over the south, so if there's one in your area soon, give 'em a call and make sure they bring some. They also ship via UPS.
After I posted the first message in this thread I've seen loaded .35 Remington all over the place - gun shows, sporting goods stores, even Wal-Mart. I would never have guessed it was so popular... and 9mm/.38, it's about a cheap to reload as you can get.
