All my power tools are De Walt, the 14.4V Combi and the 7V screw driver make an awesome team for general household tasks, putting flat pack furniture together takes minutes rather than hours. I must admit that I was swayed by the natty black and yellow scheme when choosing my brand
That said I have never had any trouble with any of the tools and they are always a delight to use; like any well made, quality, professional standard kit.
If however you are after maximum bang for your buck then I would have to recommend you buy a corded SDS plus hammer, it will drill holes in your walls just by looking at it. The problem is when you get carried away with a small demolition task and s,uddenly find, half an hour later that your house no longer exists!
