Agreed. I wouldn't waste my money with any LLN.cc, also wouldn't be in a hurry to purchase random LLL.cc as I don't see them going up in value soon. I would focus on popular keywords if investing in the .cc extention
LLL.cc in dictionary words and popular first names could be worth getting if they're still free- but you probably won't find any.
You'll sometimes find these available in the ccTLDs for sale section at $100-ish (or that's the price I always seem to notice).
Obviously, there will be some good LLN.CC names, such as mp3.com
However, given the fact that there are still numerous LLL.cc names available, I wouldn't rush out right now to acquire XJZ.cc
