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.
I'd just post it on a local internet listing, like kijiji.ca where I live. A fellow bitcoin enthusiast will contact you and buy it with cash, or bitcoin. easy, maybe not as safe as the guy is coming over to your house / meet in public, but whatever you screen people based on their grammar

OF course, this is only valid if you actually sell at a reasonable price, if you want to scam people into paying really high prices, like on ebay, then...well...go complain somewhere else you cant sell ༼ つ ◕_◕ ༽つ s5 should be able to sell for 300$ no?
