I will elaborate a bit on mine. I bought the kit because I knew NOTHING about leatherwork. If I could start over, I might consider NOT getting the kit, especially if I had done a bit of research first. The kits contain a bunch of projects, some of which are less useful than others. All of them have excellent instructions to teach the basic process, but all of it is geared toward Tandy products. This is fine if you'd like to make kit type items, or for learning how various items are constructed.
I found very quickly that I did not like the finished product as it looked generic. I also quickly outgrew the tools supplied with the kit. They are functional, but as with any skill, good tools are more comfortable, easier to use and produce better results. Pro grade carving stamps are a perfect example of this.
The Tandy kit was 80 dollars USC, and of all the things that came in the kit, there are exactly three of them that I still use. The 104 backgrounder, the swivel knife for my beader blade only and the briar brown hi-liter. Other than those tools, I have purchased replacements for everything else.
Truly, 80 dollars is a drop in the bucket of the money I have spent on quality tools, but I still say that it was a good place to start.
