I'm thinking of getting a combo machine (Planer/Jointer) and have been following the threads about it. My price range puts me with the Grizzly GO634XP 12" Planer/Jointer W/Sprial cutter head. Right now I have a 13" Delta benchtop planer and an old 6" Jet Jointer. Will I notice a night and day difference with the combo machine vs. what I have now? Thanks for any input, Sean
