I don't think the first 3 are worth much, not sure on their uses and the extensions aren't all that great tbh. I guess reg fee to what the buyer is prepared to pay.

Asia-cup.com would be worth something if the dash wasn't there, but if you found someone interested in creating a site for this sporting even, $50 with ease.

The third one has more potential, it's slightly long though, probably the same as asia-cup.com tbh.
