I just dropped a double premium LL.vc after holding it for three years. Goodbye $100.
There are many of these available and the $35 (Dotster) renewals are tough.
On the other hand, the major extensions are about to sell off their LL's and there is bound to be a lot of interest generated by that. At the moment a lot of registrars and web hosts do not even accept LL domains. I can't imagine there are many end users interested in .VC.
If you can afford it, one LL would certainly be cool to own. And a small amount of interest will quickly drain the available LLs in .VC and the other few extensions where LLs are available cheaply. Only 676 possible LLs and 100 possible NNs.
