Paul, the body composition analyzer I have is:
Innerscan Scales. It's pretty nice -- it shows body fat percentage rather than pounds, but it does show the weight of your muscle mass and bones, so that's easy to keep track of.
This year my resolution is to never worry about losing weight and never to go on a diet. I am focusing on building strength and suppleness, and this little machine will help me with some of my specific measurable results as far as muscle and bones go.
Good luck!
