wide range
Estibot also tells you what happened to the .info and .tv versions ($28 and $900 respectively)
Personally I think that the Channel (low number - mainly 1 to 9 but 10 may creep in) market is probably best suited to .tv but .com would prob sell for more - cctld for local content next best, .net next best, .org is probably the next best after that so I would guess low to mid $xxx as a pure domain name. However, since there are/will be prob a few channel 10's around the world so it may well be worth more to any of them.
