I'd say FDI was better than most of the above. The "I" could stand for "Inc", "Institute", "International", "Industries", or "Investments".
On the UK Register of Companies alone there are 15-20 "FDI" companies. In the US there, would surely be 5-10 times that. Globally, maybe 500-1,000.
.info is growing rapidly and LLL.info appears to be attracting a following. My advice is to park it on Sedo and wait for a buyer to come to you.
