Tool advice. I want new tools. I don't need them. I don't do anything. But I want them so... Anyway, battery powered. Prefer Lowe's and not HD. Open to other sources. Looking for advice on which brand to go with for best selections, results and maybe economy. I want to start with a drill type that can also be used as a power screwdriver hopefully. And a sawzall type saw I can cut a 2x4 protruding from the driveway. Obviously it would cut other things also. I know basically nothing of battery tools other than seeing 18V/20V used a lot. So any advice and/or reference material referrals appreciated. Thanks.
