Just an option for you to consider...
For just a little more (relatively speaking) you can buy a brand new EVGA SR-2 from Newegg. Currently at $430, less $30 MIR, plus $8 shipping, for a net cost of $410. I realize that's nearly $60 more than your stated price but for that additional $60 you get a NIB product with all accessories and comes with lifetime warranty (provided you register product within 30 days of purchase).
