They're on eBay too. You may see some good deals with a hot summer afoot as they're power hungry. But with LTC on a consistent rise, it may be tough to get a handful of them at a competitive price from third parties. I hope you get what you're looking for!
EDIT We may be willing to get rid of A Titan, pm me if you're interested. but I'm thinking you won't like the asking price:D
Ya man, people that had paid off scrypt ASICs running are doing very well right now...
And every ASIC I bought 12 months ago is still running (100 MH of Gridseeds and Zeus) = amazing.
But best bet is local listings like kijiji in Canada... but you MUST have free power.
And you MUST trade, not just dump the coins...
For the coins I mine, I trade at least 10-20 times mining volume...
As time goes by you get better and better at mining/trading the most profitable coins.
