No, butterfly labs has been under a lot of heat lately for not delivering on there products although, that is a last gen miner from them it's also overpriced. I would reccomend 5 antminer u2 at $20 so $100 for the miners plus say $30 or so for a nice powered usb hub. Here's 2 mining profitability calculators I found awhile back.

Also, I don't reccomend buying from Amazon since most of the prices are higher than they should be. eBay is where I get all of my miners and I've never had a problem.
