What you paid for it is about the real value, that new almost $1,000 price is too much for that computer.
Since it's not too old, the $350-400 price is about right. Usually upgrades to systems don't add much to value, basically the new hard drive you added is just rolled into the original cost for used value not an addition. Put it on ebay with a starting bid of $350 and see what you get.
New that is 549 and it is very similar in specs, just a generation newer. I'm guessing a fair aftermarket value on yours would be 350-400 on the high end.
It's not intended to be the same laptop, it is a different machine with better specs. The hybrid drive won't increase the value, in some cases it would decrease it as many don't like the nature of ssd/hdd hyrbids.
