Nice box.

As for what it's worth? How much did you pay for it? What you could get on craigslist? Probably $75-$100. I doubt if you could break $100, quite a bit of competition out there. Plus 3 digits for just a top box is going to limit it down to very specific top boxes. Depending on your location of course. If you want the most money, stick it on ebay.
Don't you think it is a bit tacky to make your first post about the value of an item you just bought, just so you can resell it?
What did you pay for it? Do some work, research it and put up an asking price. People these days, always want handouts.
