When we moved, most of the tools were old and left behind. I kept my made toolbox, a sabre saw and a cordless drill. When I worked on my antenna project, I realized I needed something more.
I researched several kits and settled on B&D. While their reputation has been tarnished, the two kits I was looking at at good reviews. They were both 20v, the MAX & the Matrix. The MAX had various complete tools that all used the same battery. The Matrix, was a modular setup. The Drill/Driver has a removable head and can be interchanged with the 3 saws, impact driver, air tool, router and sander.
I purchased mine with the carry bag, 2 batteries, Drill/Driver, Reciprocating Saw, Trim Saw and sander. So far impressed with the set and it should work fine for my DIY projects. I can add more attachments over time (Read Birthday, Christmas Etc.)
