150 pounds is a good weight for an anvil. You might want to go even bigger. That means you'll probably end up paying around $450 to $900 for a quality anvil. Really anything you can find between 100 and 300 pounds is pretty good. You could be able to get away with a 55 lb anvil, but it gives you a lot smaller of a surface area to work with.What is a good anvil size?
