I have the 40-690, basically the same except no lift arm holder and they improved the on /off switch so dust doesn't get in as easily as mine. I've had mine for 8 years and use it alot, starting to hear some bearing whines in it now so will probably be replacing those before to long. I love my saw but I wouldn't suggest it for compound cuts. Better to go up to an Excalibur of better if that's your thing
