got a hilti te6a. nice bit of kit, but I'm on me second charger, and I think the battery's on its way out. but that is after about 6 years of horrendous abuse (believe it or not, my core drill packed up one day, so being stumped, i even drilled a 5 inch core with this thing - took a while, but for a cordless ---> mint) . got one of those hitachi 24v sds too - cracking little drill, great value, nice and dumpy too, good for tight spaces. bosch gbr 24v sds is pretty good too. got/had some dewalt stuff, but they dont like being dropped - cases seem to be made in number of sections, seem weak to me, but i figure we're all different.
