I can tell you who to avoid. Don't buy a kit through Dixie Gun Works.
I bought a three band Enfield kit from them a few years ago and the stock wood was horrible. It WAS walnut, but that is about all I can say in it's defense. It was not immediately apparent that the wood was faulty, and I set to working it with a rasp. Not long after, I noticed that there was a small hairline crack right above where the lock goes. By the next day, the crack had gotten bigger.
I called Dixie and told them the problem. While they were polite about it, the pretty much told me to take a hike. Obviously it was my fault.
Well, I had to make do, so I went ahead and repaired the crack and moved on. As the project progressed, it cracked in three more spots. All of the cracks were along the same grain line, and said grain line moved in a slow corkscrew around the piece.
Well, I went to a re-enactment up in Georgia and Dixie had a tent set up there. I walked in and showed the piece to the man. My repairs were fairly well done, and he gave me the "what are you complaining about?" brush off. I politely told him that I would never buy another kit from them again anf left.
I have yet to fire a ball out of this rifle. I am scared the stock is going to splinter under recoil and impale me. So far I have just used it to burn powder at re-enactments.
Sorry for the long winded post. Others may have had better luck with Dixie, but they dropped the ball in my case.
YMMV
