While I have a considerable number of .TV domains, very few were acquired reg fee. Most were acquired as drops or on forums. I believe there is still opportunity, though limited, pursuing .TV drops. Also it is worth checking the DomainStore.tv newsletter. Though many names are priced for end users, there are some deals as well.
I recently registered 3 .TV domains, all one words. They aren't the best ever but they aren't pointless words either and they only cost me the reg fee, which is pocket change when compared to the premium ones.
I plan to develop them and keep them for a long time. Over time, most one word .tv domains will be worth a lot unless they are too random, long, or difficult to remember. I think there are very few left that don't have a 'premium' price tag. The ones that are left, are getting taken every day.
