I don't know how much I don't know about woodworking, but a jointer was one of those tools that really clicked for me. I don't know why, but between the jointer and planer (both Powermatic), I found myself able to do things I couldn't do before. The top of the bench above is actually two boards we connected by running the edges over the jointer, then used the domino joiner (Festool) and glue to join them. After the glue cured, we ran the board through the planer and drum sander. After final finishing, you can't see or feel the seam where the two boards come together (close inspection may reveal grain discrepancies).
My buddy also has a Sawstop saw. Not only is a great saw (I've only used crap tablesaws before, but this thing is awesome), the safety aspect is impressive. Someone who knew what they were doing could probably do what needed to be done with just the saw, but I found the jointer useful all the same.
The two woodworkers I know are super helpful and freely offer their time. It's as if they're trying to spread the disease.
