Haha I was about to say the same thing Doug, if you want to learn about a flitlock and the mechanism you should get a real flintlock then you will better understand the handling characteristics and such.
Also I have a traditions penslyvannia and its a great gun except for the touchhole being a little small, however I havent heard many good things about the deer hunter, Its the cheapest one on the traditions lineup.
You might be better off with a hawken style, i beleive you can get them in synthetic and flint. Also the hawken is a more traditional stlye for shooting and handling. It also has a nicer more refined stoc line than the deer hunter.
