With the high cost of renewals, I really don't see the value in LLL.CO names. There have been a select few that have sold for a decent amount, but they really shouldn't be used as the basis for valuation.
I'll admit I bought a few and regret that decision. The one that I have now will probably not be renewed or sold far below cost.
I personally would rather own premium LLL.US or LLL.INFO names before .CO names.
