I was browsing through a book on woodworking projects at the store (this one, in fact, apparently available for free to Kindle owners with Prime), and ran across the following paragraph in the tool recommendations:
Choosing a biscuit joiner is going to be limited by what’s available at your home center – most stores will have one or two brands at most. If you’re ambitious, you can find a couple more to choose from at a local Sears.
This book was published in 2012. All the diagrams were done in Sketchup. It has its own web site for supplementary material. In the back it lists the URLs of 20 online suppliers, most of whom carry a wider variety of tools than “your home center” or “a local Sears” (if those still exist…). Now, admittedly Amazon’s biscuit joiner category is a bit confusing, given that it somehow includes soil compactors, cabinet legs, Super Mario Brothers magnets, jointers, electrical cover plates, and a CD by Vagon Chicano, but I’m pretty sure most tool-users were aware that Amazon had good prices and selection back in 2012, and the suppliers they did mention in the back included Woodcraft and Rockler, who have been known to sell a tool or two.
Basically, this is a “column compilation” book, and the part on selecting and using tools obviously didn’t get any editing love when they updated it. Hopefully the editor of the brand-new 2016 edition has replaced this and other dusty 20th Century artifacts.
[and, no, I’m not in the market for a biscuit joiner at the moment; it just happened to catch my eye]
