Why this blog?

I create blogs to help me organize projects and information. In this case my wife and I are very interested in vibration technology for exercise. She's been going to her acupuncturist and he has a vibration machine that she really likes. She thinks it'd be great for us to have one at home. Unfortunately the one she has been using is an $8,000 machine--a little out of our league, so I'm looking into options. There are lots of other machines that range from a couple of hundred dollars to $1,000+. I need to know if they are worth it or just pieces of junk. This blog will help me to determine if I want to buy one or not. And I'm always welcome to input and feedback.
