T/C Black Diamond, it is everything the manufacturer says it is.

Top of the Line: Thompson Center Oncore-- this is a great gun. around $500

Or a little cheaper: Knight American Package Kit-- i have this gun and it is an awesome shooter for a pretty cheap price tag. $125 for the kit

Both of these guns are In-lines

I looked at an Austen/Halleck halfstock flintlock .50 roundball, Hawken-style rifle at the Hunter's Den in Waynesboro PA last week. It was a very well-made gun, sparked nicely, and had a good adjustable doubler-set trigger. It also had a full-buckhorn rear sight that I would have had to scrap if I were to try to use the gun for hunting!!

Depends if you want to go traditional or modern in-line.Traditional I would check the T/C or Lyman line out.For the modern In-line there are so many great ones to choose from.My favorite is my Knight Disc.I have a Ruger 77/50 but still haven't tried it out.I would recommend if possible shoot different ones before you buy one. If you have a local range go and see if there is anybody shooting a ML.Talk to them ask questions.Once you decide which one you want,check different shooter suppliers and compare prices.There are allot of good buys but you have to search the catalogs.Check your states regulations which are legal to hunt with. Ruger Redhawk

I have built many front loaders over the years and have used them for club shoots and for hunting. All the ones I have built were 50 cal. and love them I have had my share of missfires in the feild on bad rainy days but still stuck with them. I just got a T/C Encore a couple weeks ago and shot last weekend and felt that the difference is unreal I think that there will be no problem in foul weather with the inline it was a real pleasure shooting this new one. like several guys have said check your DNR to see what laws you have in your area before you buy. which ever you go with try different powder loads since all guns have a mind of there own and shoot different. Good luck and just practice.
