[Buy new set or stay with what I have]

I have the Craftsman 75th Anniversary tools set I bought back somewhere around 2000- 2003. I more of a weekend warrior, well I know what I am doing, but just don't have the time. Anyways the 19.2 batteries no longer hold a charge and not sure what to do. It will cost about $70 to get two new batteries, but after reading the review for the Milwaukee V28 on the home page, I can get a new kit for around $600. Am I better off just keeping the kit I have or should I upgrade to the Milwaukee V28?

I would like to see this information also. Can you either post the info or pm me with it.

Very nice. How long did it take you to make? On a scale of 1-10 where 10 is hard, how hard is this project to build from scratch?
