I have had good luck with Rockwell and Mastercraft which is a Mernards brand. The guarantee is solid with the Mastercraft. BTW, I really hate shopping at Menards. They have a high turnover of staff and staff with kids who don't have a clue of what they sell or where to find what they sell. As the economy tanked, their crew is much better but as soon as housing takes off, look out. Back to topic and off rant.. I have gotten a lot of good use from Sears 18v C3 lithium combo tools. My woodworking is home carpentry.
