I'd needed a circular saw for some time but I resisted because of the expense. Finally, While tearing down an old fence, I caved. I bought the Ryobi CSB121 Circular Saw because it was the least expensive saw I could find that still seemed to be reasonably well built. I'm glad I did. It's got all the power I need to cut up boards. And it doesn't look like it's going to stop anytime soon. While it may not be professional quality I think it's plenty good for the occasional user.
