ASIC is the best, Where to buy I don't really know. Looking for it too

because it's always limited stock so really hard to get... To build your own I think it will be hard. BTC is the main currency and worth much more than LiteCoins. It's easier to get but worth less

So if I get it right, for example:
I'll mine BitCoins 1 hour: earned 1 BitCoin> Value=100USD
I'll mine LiteCoins 1 hour: earned 4 LiteCoins> Value= 100USD
So I guess that it evens out?
Now I still want to know about buying and building BitCoin Miners with ASIC Hardware??
