Really depends on what you want to do with it. Re-enact-then you really should get
either a repro-Brown Bess or Charleville-to do a Continental/Militia or Crown Forces impression, or a Pennsylvania/Kentucky style rifle. Those will take you from the Revolution up to the Mexican War. Mountain Man?-a Hawken style rifle. Do you want to be 100% historically correct or just "close enough"?
I would also recommend reading up on black powder and flintlocks before you buy, more to learn how they really work and the pitfalls you may encounter.
