George - Your saw was likely purchased before hybrids were available, as was my GI contractor saw in 2003 (which was sold for a hybrid in 2005). Hybrids have many of the advantages of a cabinet saw. This isn't a comparison of our former saws to a hybrid, it's a comparison of like-priced new saws for a would-be buyer. If the savings were significant, it would be an advantage for the PM64, but that's not the case. Even though the PM64a is a nice saw, at even money it lacks the design advantags a hybrid offers....both saws will cut wood well....that's not the issue. The aspects listed are advantages in favor of the hybrid... individual opinions of how important they are vary, but they're advantages nonetheless. If the belt on your saw was shorter, you'd have more power to the blade than with a longer belt, plus there'd be less vibration....can't imagine that anyone would rather have less power and more vibration if given a choice. One thing I didn't really get into is the leverage caused by the outboard motor on the trunnions which can cause problems with the alignment, plus can just plain get in the way....there's simply no need to go that route any longer unless the motor needs to be removed frequently. There are feature differences like the fence, handwheels, guard, throat insert, etc., some of which may favor the PM but those are mostly subjective. Blade selection and alignment will ultimately determine the end performance of both.
