Milwaukee, again, has produced a superior product.  The tool is very handy and really does work in tight quarters, although I use it for a lot of different applications.  The trigger is one of the best I have used for controlling the speed of the drill.  It gives you a feel for the speed and is very precise.  It fits in your and perfectly and has never bogged down.  Ever.  It is a litle pricey but it's a drill that is used a lot.  In no way is it limited to tight quarters.
