For the price, the Lyman is currently the best OTC flintlock for the buck, and I have tried them all, trust me. The Blue Ridge Hunter from Cabela's is a good rifle, and would be my second recommendation. (My first recommendation IF a person has to have a full stocked longrifle)
A T/C would be my third recommendation, but their flintlock lock is a bit clunky, and often needs minor adjustment. The Traditions I got had a very weak lock. They make a very good caplock, as does T/C, but one cannot skimp on lock construction with a flinter and have good results. Both T/C and Traditions seem to be good caplock makers who then adapted a caplock to flintlock while trying to keep costs down. (oops).
Dixie seems a bit pricey, what with semi-custom makers producing comperably priced rifles with much better components at the same price.
Pedersoli is waaaay overpriced with their muskets and trade guns. For the same price one can get a very good semi-custom fusil or trade gun, and even a good semi-custom longrifle. (For a $1000 price tag you'd think they could properly harden a frizzen!) If you want a military musket, Loyalist Arms in Canada is marketing a much better copy of a Bess, very shootable, and with a bayonet is $300 cheaper than the Pedersoli.
FINALLY ...., IF ......, the flint-bug bites you hard and you want to upgrade to a better gun than your first choice..., check with local clubs and guys who shoot 'em. You may find a shooter or two who are looking to give one of their well cared for rifles to a good home for a very reasonable price.
