I am not sure how it would play in your native language, but if you think you have to have one, I like the ones that the domain and the extension spell words...such as
ami.sh (a religious sect in the US plus a woman's name...ami)
barr.io (a spanish language for small urban community)
They both cost the same so there's only one thing left...your preference.
Gotta love it. The second most famous will soon be hit.name.You are talking about "domain hacks", the most famous example is del.icio.us.
