Track, Jedediah-Starr, Possible Shop, Dixie Gun Works are all great to deal with.
I used to live and work in your area, still have folks down there until moving an hour north a few years ago.
Scour the pawn and gun shops, there are plenty of them in your area.
Last couple of visits to Gander, they had poor selections and too high of prices. Bass Pro in Orlando however, had BP pistols, caps, round ball, etc. in stock and at reasonable prices.
I'm cleaning up 3 .54 caliber CVA rifles, 2 Mountain rifles and a Hawken Hunter.
