Honestly I don't think the name has much value.
As a rule hyphened names are worth less. There is one hyphen for only 3 letters.
Just imagine a radio ad campaign where the name would be read aloud and spelled out.
Even though they are sometimes OK when it's 2 words. You should not gamble on the fact that some organization might be willing to purchase the .com version of their name one day. Maybe they will, most likely that will never happen.
So my verdict is reg fee, not $0 because it has some traffic. Good luck.
