Some Craftsman is junk, some not.... the 21828 is pretty much identical to the Ridgid R4516, both made by TTI/Ryobi. No idea how good either one is. I don't have much experience with portables, but I do know that the Bosch 4100, DW744, and Ridgid R4510 are typically the most highly regarded. The DW745 is smaller than the 744. I also know that setup and blade selection are huge factors in the end performance of any saw. Good luck, I'm sure someone with more insights will be along soon.
