I picked that drill up for £99 at christmas. The batteries last a good time, plus you get two so always have a spare (<=30 mins charge time) I just used it almost constantly on for an hour odd. The fan keeps the motor cool unless blocked (which I seem to do when holding it two handed) you soon feel the heat anyway
The driver (even in drill mode) is outperformed by Festool but I guess that is the case for most other makes
But I felt rather inadequete whilst screwing noggins into some joists a month or so ago. My builder mate had to finish them off with his Festool when the Makita gave in about 3/4 through. I think the price difference in drills was about 4x though
