I'm a buy the good stuff as you need it guy. Freud sells in Home Depot and many of the common bits are there waiting for you to rescue them and put them to work. The more complex bits, such as door making kits, I prefer to buy either direct from Freud online, or to get from another maker--my favorite alternative is Sommerfeldtools.com. I also suggest you look up Marc Sommerfeld's videos on YouTube. He is a pretty skilled cabinet maker and his how to videos show really good technique using fairly simple methods. I think there are about a doqen of them now. You can get a video downloader app and save them to your computer for rpeat viewing. I often review them when making something because it's easy to forget the details.
The more I do, the less I accomplish.
