I would agree that you should go to a gun shop and check out the different muzzle loaders before you purchase any. After that give
http://www.gunbroker.com a look though. I' ve bought my last 3 guns through there and have been completely satisfied! You have to buy a gun online through a FFl dealer, mine charges me $15 and I have saved atleast $100 on every gun I' ve ever bought this way.
