Your renewal will be whatever the renewal price is with the register you buy the name with in the first place.
This will normally be anywhere between $25 and $35
If you are serious about LLL.tv names - forget buying them direct. It might be cheaper if you buy them from resellers - most of whom got the pick of the bunch at $9.99 during the frenzy/landrush/goldrush period.
TV is cool, but really not worth spending hundreds on LLL.tv when you can get then at $XX from members here.
There is a whole new .TV renewal fee system for now and forever.
It all changed on March 18th of this year.
Any .TV domain Name Registered after March 18th of this year is and will always be reg fee. Thats it
and like Jimbo said,
spend your money wisely.
LLL's have always been a niche that people have invested in with each and every extension out there but believe me,
.TV is an entirely different animal!
and there ARE some killer deals in the AfterMarket now
