Ok, I'm a DeWalt guy and have found their stuff very good over the years. however, I am not a heavy, daily user. It's clear thatmanufacturers have different quality in their ranges, so one drill at the cheaper end may be pretty poor compared with their top-end offering.
However, just to throw another range into the mix, at the Men's Shed charity where i do some work, we received a donation of a set of Ridgid cordless power tools and they are built like the proverbial tanks. One member sourced spare batteires while in Canada as they are not easy to get in UK. We run DeWalt in the Shed in the main, but it is the Ridgid ones that get grabbed first for any project.
