A number of people are really unhappy with the quality of the stamps supplied in the kits. They are lower quality than the stamps Tandy sells individually. So you may be best off the take a second look at the stamps you are most likely to use and skip the kit.
As mentioned previously, look at some patterns the style you want to carve, and get those stamps first, plus maybe some larger and smaller bevellers. So as soon as you get into the Tandy store ... go look at the patterns and pattern books, see what tools are used, and get those ones. And buy a few patterns too. Also some scrap pieces. The books and patterns by Stohlman reference some tools no longer made, so you need to cross reference to something that is close to the original stamp.
