Hi, I'm planning on selling my year old laptop, in order put more funds towards the cost of my new computer build. It's an HP Pavilion DV6t-6b00 Intel Core i5-2430M 2.4GHz 8GB 750GB 15.6" with a Intel HD 3000 Graphics. It's in perfect condition. I'm assuming it would be within the $300-400 price range. I was just hoping to get some suggestions on what a laptop with these specs usually sell for used? Thanks in advance.
