I'd have to say my favorite tool is my makita miter saw. I tried to convince myself for the first couple years I didn't need one because I didn't want to store it, pay for it, or carry it. But of all my tools, this is probably my favorite :thumbup:. It does suck to transport because it's heavy and has a big elaborate stand but don't know how I functioned w/out it.
I would also have to include a Skill skillsaw. I got it for christmas one year and figured it was junk so I'd just use it for demo. That poor saw's been to hell and back and still kicking!!
Best deal would be the Fluke voltmeter my neighbor gave me. It's a 87 III true rms!!! and it was freeeee. I could have kissed him. He's an electrician and an all around good neighbor :thumbsup:.
Worst tools would include Dremel for sure, a Dewalt sawzall, and Milwaukee 18v cordless kit- the batterys are garbage!! I do like my Rigid cordless kit (although l/i batterys don't charge well when they're cold) and pretty much no complaints about any of my Rigid tools.
