The real benefits of YC though are the focus it brings you, and being able to get access to the YC ecosystem. Oh, and being able to attend Demo Day, but with so many companies in the YC program, I think Demo Day isn't what it used to be (I think you get 90 seconds now?).
We would have loved to have had access to those resources, but since we had already invested far more into our company in terms of cash, it's hard to justify giving up that much equity for so little. Kudos to Sam for the new program.
