Query: Overpriced parts needed for repair.

They are no longer worth the money. Quality has gone down and parts prices have gone up. I have several of these, and every time one fails, it costs an arm and a leg to buy a new part. I have finally given up on DeWalt and just cannibalize another drill to get a part without going broke. DeWalt is useless in helping me with repair advice, and small parts are not available to the consumer. All they say is "Take it to our repair service."Their battery packs are horribly expensive, too.
