I have to agree with Doug and Mike about the battery power. Unless you are using it on job sites where you can't guarantee there will be power then you will be better off with corded. More power, less weight, better balance, and no recharges. Not to mention that if you buy a good one it will last a lifetime, unlike battery powered. I have a few battery powered drills that would still work if the batteries were good or the charger worked. Unfortunately it costs more to replace them than new ones cost. I keep one battery powered drill around these days and everything else has a cord.
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.
