Ok there is the 2 different TVM shops, Track of the Wolf, Sitting Fox, P-Creek, Knob creek, Jim Chambers, Jedediah Trading Post, ummmm and many many others. They all make decent kits as far are experience goes and money thats up to you Jim Chambers kits are nice guns and most inletting, sights, breeched, are done for you but you need to drill the torch hole, or drum hole. Tenn Vally Muzzleloaders all this is done and they are cheaper but in my experience the wood is lower quality still great company and like I said cheaper. Sitting Fox in Michigan is a decent company to work with just ordered a 54 cal swamp coletrain barrelled early lancaster with super premium wood for $799 an extra hundres they will inlet the lock, trigger, cut and install sights, and underlugs. I'm deployed and it was sent to the old mans house and he sais it looks great and the woods has about a 95 percent curl. Havent built a TOTW gun in a while but other then a tight barrell channel they have been good kits, again you might wanna spend the extra money and have the sights cut, and barrell breeched and lock and trigger inletted, makes it easier and saves alotta time especially for a newbie. Jedediah Trading Post another Michigan based company is solid company too, and they also offer to inlet, all the fun stuff, and cut sights and install lugs. All are pretty close in price other then the Jim Chambers kits which typically run about 100 or so more overall but worth it in the long run and they are great people to work with and guns hold there value but recommend to make it a second gun build. TV Muzzleloaders is a solid easier first build and would prolly be the cheapest overall. Just make sure you pay attention to what locks come on the kits. I know most come with a large siler lock. Also is you want steel versus brass, or even silver the company makes a difference too. Hope this helps I am not biased and build many different guns from different companies, I like and usually only build steel parts on my guns so I jump all over with companies.
