My wife just got me
this one for my birthday a few days back. As it says, its pretty light for a drill. I haven't used it yet, but I love all my other Makita tools.
I previously had a 14V Ryobi drill with Ni-Cad battery. Worked ok for a while. The packs never held a great charge, and finally both went bad. I never ended up replacing them. Until then I had an ancient 6V Craftsmen single speed drill. It got me by just fine until I just got my new Makita. The point is I don't think you need to be real picky about this. Most things out there will do fine if you don't use them day in and day out.
