Reg fee. Unfortunately, being the previous owner of this domain name, I'm in a spot to know.
In the year I owned it, it got 14 uniques at fabulous. And I didn't get a single inquiry for the domain. It did make it's reg fee thanks to a generous visitor, but wasn't stable enough or brandable enough in my opinion to renew it. I shouldn't have let it drop, though, as I'm sure you could get at least a few bucks for it as long as you don't wait until the last month to sell.
Best advice for you would be to develop it into something useful. It's definitely brandable... but brandability by itself doesn't really sell domains.
