I had a 20 inch Woodtek planer. I sold it and bought a DeWalt 735. That huge planer took up too much space and I decided that I really did not need that much planing width. The DeWalt serves me very well since I do have a large dust collector that I connect to it.
On the other hand, I wish I had a larger jointer (mine is 8 inches), but I doubt there is enough room for it. When I need to joint a wide board, I take it up to Santa Fe Community College and use the 20 inch jointer there.
Once I complete the two dressers I am currently building, I don't think I will build any more large pieces. Maybe a dining table, though. It's just getting too hard to lift big pieces.
