Query: Not very useful!

I am rather disappointed by this book. The information provided is quite rudimentary. Much of the book is dedicated to the building of a router table (a particular design). So if you are looking to buy a commericial table, don't expect to find any help here. In the routers sections, it fails to actually recommend particular routers that are good for router table use - by writing just in general terms instead of citing specific routers manufacturers. The book lacks in going in depth on the various techniques on using the router table.
