I would definitely advise against it myself.
Once in a while I look up 1 or 2 absolute killer .TV 2 worders with a dash, and think I might reg it, but I never do. I regged one upon entering domaining, but let it drop. It was not worth it, just a rookie mistake.
I do believe there are a few that could work, but not many.
Actually a .Tv NP-er here regged something like Car-sales, or used-cars.tv and in his appraisal thread I said he wouldn't even get reg fee for it, and I believe he sold it for about 30-40-ish so it IS possible. Not earth shattering at all, but too much of a risk, IMO.
just be careful if you decide to change your mind.
Having said that, In this extension we are still very early, and things are heating up quickly. There still are a bunch of incredible tv reg fee domains out there, and don't forget to check out the .TV Marketplace here. Some of these tv's owned by members here, you can really grab for a great price.
Good Luck to you,
Vito.
