Battlestar Galactica Blood and Chrome had a budget of 2 million. And that was considered a pilot. Once all virtual models are done the budget per episode should have been lower, as these virtual set could be reused from different virtual camera angles and so on so I think it is safe to talk about lower budgets per episode like .5-1 million range, with some exceptions like highlight episodes and season finales, and could be lower than .5 millions for bottle episodes.
Blood and Chrome was given a $2M budget initially, but, I'm pretty sure it actually cost in the neighborhood of $6M, because of overruns. But, many Pilots cost considerably more. I thnk Terra Nova was over $10M, as was LOST (In fact wasn't it over $20M?)
