Kudos to the organizers for keeping the registration affordable. $199 for the early-bird seems very reasonable. I recall that the goal was to pay for the venue plus a little contingency.
That looks like a great conference! I wish I could go, but I'll be out of the country. It would be great to meet everyone.
You should go to clojure-conj (I certainly am). But if you can't make it, you might be interested in Strange Loop (St. Louis Oct 14-15), which also has a strong Clojure focus: http://strangeloop2010.com/calendar
So far, so sad. Google maps says 15 hours and 9 minutes of traveling. I hope videos will be available.
