Tom the battery powered tools are handy but the batteries go and depending on voltage can be rebuilt for around $60 and replaced for $80 to $100 per battery. While the cord is a nuisance at times, a corded model of really good quality can last the life of the owner. If you are a contractor it's easier to justify cordless. For the DIYer it's a lot harder. Most of the old drills I have that need batteries would have to have the packs rebuilt now as the original packs are no longer available nor are the chargers. Like computers they seem to have a planned obsolescence engineered into them.
I keep one cordless drill around now and everything else has a cord. I know I'm not alone in my opinion as this has come up before on the forum and quite a few other members have stated the same thing.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
