Same here...I could fit two S3's into my farm but I am in a better position to ROI than most and this is +150 days even for me.
People don't buy stuff with no chance of breaking even anymore!
To provide a data point for folks, last week I bought two Antminer S3s and a Corsair RM 750 off eBay
shipped across the US (3 days) for $247.
I realize the ROI is tough to hit, but it's a hobby and I'm in the long haul with this stuff.
FWIW, love the machines! They've been a hair shy of 440 but super consistent there.
Longing for an S5 or two.
Happy mining everyone

Thanks, TDM
