Depends if you want to see your money again. Those have been discontinued, if you're going to buy them, get a few sellers in a bidding war to get prices down. You can get them real cheap if you're smart. Lots of people have lots (like 1000's) and want to get rid of them.
They only produce like 0.0003 BTC per day.... If you want it for fun go for it. But like I said, you may never see your money again.
I call Bullshit! with skyhigh price you cannot find these for cheap anymore maybe a month ago sure you could cop one for 13 bucks but now everyone is jacking up the price to 26+ bucks a piece again.
