My saw is a 23 year old Hitachi CM40. It's a very good saw, still runs like a top. I am starting to have troubles with it occasionally, since they don't make it any more and parts are obsolete, so have been shopping for a replacement. Being on a fixed income I cant afford a 788. Scroll Saw Woodworking magazine did an article on the Porter Cable and gave it high reviews. Also, Steve Good did a review, (video on you tube), and he also gave it a good review. A buddy of mine bought one at Lowes ( $199 plus tax) and he loves it. He had an issue out of the box. The lower blade holder was stripped. He called Porter Cable directly, they wasted no time sending him a replacement blade holder. Then he was off to the races! My new saw (hopefully this week) will be the new Porter Cable.
I hope this helps you. Good luck and happy scrolling.
