Excellent combination of letters.
FYI is a frequently used abbreviation amongst the new-age internet users.
Used in chatrooms, general conversation etc. etc.
I'd say possibly around $150 for a reseller but end-users should be the category you should be targeting as the domain could be invaluable to them.
You might even see high $xxx - low $x,xxx for an end-user.
I think there will be a market for the L-LL.coms, especially the ones that obviously stand for something like FYI. I also like names such as L-RV.com where the 'L' can be a letter representing an RV company name. Or L-PC, L-MH, etc,.
