I built a desk ~10 years ago. I had fun, learned a lot, and haven't used most of the tools since then.

I think part of what I learned is that it's worth it for me to pay a professional.

After building 7 more tables they might actually ROI on the circ saw and orbital sander and consumable supplies. Then they just have to start working down the capital costs of the table saw, router, miter saw, and clamps.
