Interesting. I've bought a lot of muzzle loaders from Dixie. I've always thought they had a good selection, from those "heirloom" pieces to quality shooters. Hmm... maybe try Track of the Wolf if you are up to building a rifle. Maybe October Country.
A few of my favorites from Dixie:
.50 caliber Tennessee "mountain", or "poor boy" (all iron furniture, no patchbox, etc.):
.72 caliber double rifle (actually made by Pedersoli):
10 gauge double shotgun (also made by Pedersoli):
