And I wouldn't put too much stock or trust in the books. I've never seen a book that can compare to what you can learn on these boards, although I admit I haven't looked at any books in many years. Still, I don't expect that to have changed much because both book publishers' and authors' primary objective is to sell books and make money. Even if they know the best pizzamaking tricks and whatnot, such information usually doesn't make it into books because the best pizzamaking tricks require readers to think a little bit and do things differently than what "common knowledge" has taught them. Also, a lot of pizza books are written by bakers and chefs. Pizzamaking is not the same thing as either baking or cooking. Consequently, most bakers and chefs are not pizzamaking experts (or anything remotely similar).
Books have a real nasty habit of showing pictures of pizzas that weren't made by following the instructions shared in the book. If you follow the book's directions, you'll never end up with pizzas that look like the pizzas in the book's pictures. So save yourself a lot of frustration and realize right now that if you follow the books' instructions, you will almost certainly never make pizzas that look like the pizzas in the books' pictures. Conversely, when I share pictures on this site, my pictures show pizzas that were made exactly how I said I made them (except when I miscommunicate). I'm sure every other member of this site operates the same way I operate. My pictures are nowhere near professional quality, but my pictures show pizzas that you can expect to make by doing the things I've done.
To elaborate on my previous post: You want a scale that measures in ounces and/or grams; most likely digital. It's easy to find such scales at places like Target and Costco for $20-$30. Mechanical scales are fine, too, but if you think you might want a mechanical scale, you'd probably want a foodservice quality scale, which would probably cost at least twice as much as the scales I already mentioned. Also, mechanical scales are less versatile than digital scales. For your needs, I'd suggest a digital scale. And try to use metric measurements (grams), rather than ounces. I've always measured in ounces until recently, and as a result it's very difficult for me to think in grams.
