Query: Great for the price!

You may be skeptical at first but the "for dummies" series always brings legit information for a pretty good price. For half the cost of other books I still get all the basics of starting my own home recording studio. It does a really good job of explaining what the basics are and what you need to keep in mind. Whether you are a full band or a one man band this book will help you get started from what equipment you may need to selling your stuff to make some serious cash.
