Problem is, it's easy to sell on ebay than anywhere else. I posted 3 S5's and sold them all the same day on ebay. I could put them out in the forums here and not get any real interest for weeks since nobody wants them anymore.
That's a fair point, but I think I'd rather play the market here on Bitcointalk for a couple weeks than sell something worth > $1000 on eBay the day it's posted and risk being scammed.
