A while back I purchased the Makita 18v Brushless Drill and Impact driver set with 5ah batteries for neigh on £300. No regrets really. I actually I do have one, I should/will purchase a 2ah battery. The 5ah last forever but are also quite heavy and if I'm up a ladder, I'd much prefer a 2ah stuck up its rear. Speed control is brilliant and I have dropped my drill off the top of a ladder and seem seems to function as new with no visible damage.
It replaced my 18v DeWalt XRP nimh drill which was also a great unit at the time but the makita DHP485 does outclass in every way.
I have the Erbauer 18v Impact driver and that is a brilliant piece of kit, the grey/black before they went to blue. If the drill is as good I imagine for the home user it'll be ok.
Thing is though, after many years of bodging it, I'm now an ardent fan of using the right tool for the job. My mains hammer drills have been handing off, having been replaced by a chunky Titan 5kg SDS+ unit, which can drill, hammer drill and hammer. If the Makita can't do it easily, then I bring that out and it chews through anything like butter. I am in love with the palmsize Makita baby SDS though and it's like to by my next purchase as I can so it being super handy when I'm working at heights, or even cycling to jobs.
If you do get a Makita, register it on their site for extended warranty. My 9yo SP6000 Rail Saw was picked up, serviced and returned for free within 10 days. And thats why I like Makita.
