I am looking to get a Samsung NP-R580-JSB1US laptop. I see it goes for $829 ($845 with taxes + shipping included)at Best Buy. I have tried looking for deals on refurbished or recertified models on e-bay, amazon, tigerdirect, newegg, etc. so far and have only found 1 used NP-R580-JSB1US, which does not have an operating system disk or the system recovery disk. Any other suggestions on where else to check? I have been on the lookout for a new laptop the last 3 days and plan to get one by 1 to 2 weeks of looking. E-mail me privately too if you have one available to sell at [email protected]
