6.5 BTC seems like a decent price for an in-hand saturn. roi would be approx 2.5 months.
I paid $6k for 400 GH/s from bitfury that was delivered at the end of last month
There's no way I'd pay $7k for a saturn now
Because there is excessive demand right now for ASICs doesn't necessarily mean that paying exorbitant amounts for them is wise
If the price of BTC falls to $250 tomorrow, you might miss that $7k you could have had today that you just offered
