I bought
CreditInsurance.us
Tried to get Insurance.us but I got outbid during pre-registrations when I went past my personal limit.
The two words are usually better and all of the major domains are all taken which is an indication that it's a good pick.
Having three words can actually hurt you I think in some respects especially if you plan to resell. It narrows your market more. But it does one good thing in the fact that it gives you an extra keywords for web searches.
Might be able to sell to a company that sells private insurance to students obviously.
Overall not bad at all.
