Really it comes down to you either buy some S7s now, or wait a moth or two till the next price drop/new model. If your going to buy now, do it. If not, wait.
Or you just pass on mining all together.
"Now pick up your skirt, grab your balls, and lets make some money" "Your gonna pass? The only people I see making money passing are NFL quaterbacks and I don't see a number on your back" -From the movie Boiler Room, one of my favorite.
Now adding this movie to the 'to watch list' haha. Massive Pats fan from downunder!
