Even with the $50 discount for full members these will probably never ROI at the price you are asking.
http://i.imgur.com/GRG41uX.pngThe calculation above assumes you pay nothing in electricity, the difficulty will never rise, you pay no additional costs for the Power Supply, cables, etc. and I included the $50 price cut in the initial cost. Even with all of those perfect mining conditions (which lets be honest will never happen for anybody) it would take a year to make your money back in LTC.
yes , you maybe right at the this calculation at the current LTC price .
but there are many other scrypt alt coins we can mine with it , if we choose the right coins and sell at right time ,it will no need that long time for ROI.
and for now silverfish is one of the good choice for cost effective scrypt miner .
If you're going to gamble, why not rent hash for less than 219$? Because for that price you can get a lot more hash than what you would get from in a year this AND you can get the hashrate at higher, short rate, for bursts, as you need a lot of hash in a short span of time, at a coin launch' to get more coins before the diff increase.
Having a little bit of hash over one year isint very effective for the ROI method you're proposing to make out of these miners. And regardless, its a gamble.
there are still diffierences, at least you own the hardware , you can mine anytime anycoin(scrypt) you want, could be more fun .
You can see now the litecoin price start to come up from yesterday.
