There's no question the DW735 planes smooth as butter. But with the problems I've had with it, I probably need something with more power. Reviews I've read on the Silent Power cutterblock on Format4/Felder/Hammer planers and jointers are impressive. From what I've seen in videos, you wouldn't need a second planer to smooth the surface.
BTW, the DW735 I sent in for warranty service seems to have been lost by Dewalt. They are shipping me a new planer.
