Turfman:
I got my Jaeger kit from the Track at last. I'm very happy with it, but: I think it's a higher "difficulty" or skill level kit than some of the others. I'll be doing some things I've never done before, such as drilling the pin-holes, and inletting many parts. They describe this kit as "fully inletted", but I find it is semi-inletted at best.
Of course the Davis lock and Colerain barrel are absolutely awesome. It will be a great gun, but plan on really spending some time with a Track of the Wolf kit. The good news is that this kit is quite a few hundred dollars less than many of the other kits, so you can save a lot of money. The swamped Colerain barrel was standard on my gun. I almost went with the TVM "in the white" rifle, but with a swamped barrel it would have cost substantially more than the Track kit.
Last year I ordered a Pedersoli kit from Dixie, the Brown Bess carbine, and it was much more easy. I had to do a lot of shaping on the stock, but it was pretty much "sand and assemble". Fully inletted, pin holes all drilled. It made into a very nice, reliable, and accurate gun. The lock is great, the touch-hole was located very well, and it has VERY fast ignition. I did have to heat and bend the cock slightly to align it perfectly with the frizzen. It also came with a really nice piece of wood, with very unique figure/grain.
