I've looked at Track's kits and will be buying one. I've built one CVA Hawken and it went together like a plastic model car, basically fit right out of the box.
If you look closeley at Track's site you will see options like having a gunsmith fit certain dovetails (if memory serves). Also they offer tap drills and taps, so, unlike other kits, some basic machining needs to be done. My impression is that I will need to inlet the tang into the stock, locate and drill holes for tang and lock plate screws and barrel pins. I think that all the furniture must be inletted by the builder as well. I plan on dovetailing the barrel myself.
You don't mention what kind of skills you have as regards wood and metal working. Your best bet may be to communicate with someone at Track as regards your skills and what is needed to build one. They have been very helpful and honest with me.
Also, depending on your patience, this forum and others may be able to help you through the process. You may have other resources to draw on for help. Following simple adages like, "measure twice, cut once and You can always take more off but you can't put it back on" as well as practicing on scrap steel and wood will save you a lot of heartache and money.
I guess only you can tell you whether or not this is the way to go for you. From what I've seen, Track is the way I'm going for my basic kit.
