Sorry it's not in my habit to post comments in the for sale thread but... if you want to make a profit (not that there's anything wrong with it), why put the bass for sale on the very same board you bought it on, just a few weeks later?
I've had basses that I sold below their value cause I wanted a quick sale, and then later the new owner tried to make a profit on it... that's ok in my book, but at least they had the decency of selling it via another channel, like ebay or through a shop.
I totally empathize with the original owner here...
