I would quickly take a 2 or 3 thousand for it, but that's me.
It could go for a lot more if you wait for the right buyer - who may or may not come. Also, you have to consider that the trend of dropping the vowel before the final r is something that could fall out of fashion - and that would put a huge dent in it's value.
I'd rather move the names that depend on transient trends or technologies, at whatever the going rate is.
If you are the one who picked it up at NJ, I assume you are planning to sit on it. NJ auctions usually represent the best that domainers will pay for something - so you would have to wait for that end-user who decides that this is his brand.
I'm also not sure what a sight using the keyword "buyer" could be. Shoppr or would have more appeal from a retail standpoint. Maybe gold buyers, or pawn shops could use the phrase, though. Or maybe a site that brings you to buyers of whatever you have to sell.
Still, up to you whether to make a quick small profit or go long for the big score.
