Our top choice is from Echo, with the DeWalt Flexvolt cordless chainsaw being a close second. We do recommend buying the chainsaw that works with your existing cordless tools, as long as it's not the Ryobi!
We take all 6 DeWalt Impact Drivers available and compare their specs to determine the DCF887M2 is the best balance of price and impact-torquing power.
We've determined that any cordless drill from a brand name company will be great for around-the-house projects. If you're a serious DIYer, you'll want the DeWALT DCD708 Cordless Drill. For the best warranty and budget pricing, check out Ridgid with their lifetime service agreement.
