Legend of the Seeker ran in syndication last year and will return again this year. I don't know what it's ratings/revenue was, but it was at least profitable enough for everyone to sign up for a second season.
In regards to ENT's $1.6 million budget. Was that the season 1 budget or the season 4 price UPN paid Paramount? Paramount produced each episode at a loss in season 4 so that they would have enough episodes to sell in a syndication deal.
