I guess I just object to paying Wilson $5k to run search-and-replace for me. And I certainly wouldn't trust LegalZoom to actually have documents written by people who understand startups.
And the other sources don't seem to provide offer letters, NDA/invention rights docs, board motions, option grants and all the other boiler plate stuff that's needed.
That all said, I suppose making it too turn-key risks entrepreneurs not really understanding the legal issues involved and getting nasty surprises later on.
