As stated before, I believe in a combination of gear and skills. Given that, I search through a lot of junk on the Internet to find the right equipment. Today I found what appears to be a well-thought-out kit introduced in 2011.

I'm searching for details; it would seem this kit is not available, at least not here in the U.S.
