Thread Setter / Rivet Nut Kit

I'm very intrested in the thread setter after using it on several occassions and would like to purchase one of my own. I have found it very handy in situations where welding a nut on would just get ugly. However, every time I look at a set to purchase it is never complete with every thing there to complement the other products that come with it. Example, it can set a klik,clinch,or rivet nut 6-32-1/4-20.Then only comes with 6-32,8-32,10-24,nose attachements. I have even saw one from 6-32 to 3/8.Wow, would really like to purchase that one. Guess what,No attachment for the 3/8 nose to insert into the rivet gun when you buy one. If I wrong on this and the description is weak let me know,still intrested at this point and still have a few rivet nuts to set.
