I've had good results with a cordless Mikita that I bought about 5 years ago. Best quality I could find at the time, even made in the good 'ol USA (not sure if they still are...?).
I also agree that a corded drill is the way to go, if application fits. I've got a couple of Milwaukees that are very good quality. Again, these were made in USA, but not sure if they still are...?
Bosch always made very nice power tools, but it seems like they have gone down the 'big box' store drain (plastic gears in a Bosch, really...?). Change product line to sell to the masses, at the lowest price (e.g. CHEAP), in order to appeal to the masses... They may still have a higher quality product line, not sold in the big retailers, not sure, haven't shopped them out in a while. These high-end brands used to make quality tools that were made for tradesmen, that demanded quality. Most stuff today is inexpensive/disposable junk.
