Well, youve probably grabbed it at the right time for the right price. I keep my eye open for "inexpensive" CCC.com's - They are dropping nearly everyday but are being snatched at record numbers. As more and more domainers enter into the market place and starting actively acquiring these, were seeing a steady rise in market pricing. I think a wise pickup, as I have recently picked up a few myself.
Judging by the current rate of growth, I suspect domains like yours will be closing in on a market price of $250 towards the end of the 3rd quarter. That of course is only my guess, but I monitor the market prices pretty consistantly. They are even available on NameBio.com (most of them).
I think a smart pickup in a time when this class of domain is starting to get a lot more attention.
