Woodpeckers Unique, high precision woodworking tools. Made in the USA.
McMaster-Carr This company supplies hard to find fasteners.
I use RIDGID brand cordless power tools. I like the Lifetime warranty.
Chad's tool box is a source of tools. They are a distributor of Bondhus bits (a USA manufacturer), and other tools not found at Big Box hardware stores.
MagicStudfinder This $20 Studfinder occasionally outperforms my $200 Studfinder. Wow!

I use the DeWalt line of Tstak cases, and other tool cases. Also some bits and blades.
We use the WORX brand 4V cordless drills on many of our furniture assembly jobs. While not suitable for heavy duty construction jobs. These drills are well suited to the type of work we do.

I own a number of Milwaukee Tool products.

I made the investment after a plastic horse collapsed in the middle of a job.
Stabila makes high quality Levels. I own several.
I own a Little Giant Extreme, M26. A friends ladder that I borrowed, collapsed (failed, one leg just crumpled up) while I was on it. I was lucky I did not end up in the hospital. People often take ladders for granted. I will not make that mistake again. After that ladder-fail, I bought the toughest, strongest ladder I could find, one of the Little Giant ones.
Berland's is a local chain of upscale tools (and expertise). I shop at the Palatine store. Their website does not allow for online shopping. You will have to call, email, or travel to the store.
I own the Black and Decker Accu-Mark Level, very useful.
Fastcap is a source of screws, magnets and other innovative tools that I use on a regular basis.
Rockler is a resource for woodworkers, and carpenters.
I shop at the Schaumburg store, and online.
