$50 for a full day, highly specialized conference, with access to the developers is a STEAL! One day general events from local networking groups around our region range from $99-$200. General Business conferences range from $250-$3,000 dollars. Other examples were mentioned above too... I agree that the WordPress community is spoiled by how cheap WordCamps are!

I'm thrilled to see more conferences like this happening and agree with Chris that even at $50, it's a low fee. I hope to see & look forward to these specialized event tickets more closely align with the value they are delivering.
