Query: Here is an awesome toy!

Hi,I recently recieved a LEGO Robotics Invention Kit and boy does it work!!! The software does work on windows 2000 but it doesn't say it does on the box. also, it can use three motors but comes with only two. The programing is relatively easy and there is all sorts of cool add-ons. I am currently trying to find where in my city I can buy the vision command. There is only one problem with it. The RCX takes six AA batteries and they only last for about forty hours of use. I recommend getting very powerful nickelmetalhydride rechargable batteries with the RCX.Other then that, though, this is really a perfect toy for the mechanicly inclined.
