I’m not sure if someone making profit on a sale while the exact same item, with warranty, sells for cheaper. In fact, I’d say that’s the opposite of a bad capitalist if it sells. And these do sell for these prices. This is partially why Fractal has offered a “Pay extra and skip the waitlist” option, to try to get ahead of the guys who are going to sell a backordered unit on EBay/Reverb. At least the customer gets a warranty that way.
Someone just sold a Quad Cortex for $2600 on Reverb. Might seem crazy to me or you, but if someone else has that disposable cash and is willing to part with it, I have a hard time citing the seller as anything but wise to sell it for that price.
