JTech chiropractic adjusting tool (like an activator, but different brand)
I had bought a used activator from one of my chiropractors years ago to adjust my wrists myself.  It worked fine for years, but eventually the spring gave out.  I got the JTech to replace it, and am happy with it.  It is lighter and smaller, and a bit easier for me to use (smaller hands).  Since I just use it for myself I have no worries about it not being all metal, and the price differential makes it the smarter way to go, in my opinion.  BTW, I am an RN.
