Glad you found it useful.

The prices on these types of laptops are really a phenomenal value, IMO. I'm guessing that most of them are laptops were leased to corporations, and then are being auctioned off cheaply once the leases are up and the businesses refresh their laptops. Sure, a Skylake i7 has better performance than a Sandybridge i7- but not as much as you might think. And certainly not enough to justify the price of a brand new laptop (for me at least).

Here's a fun video that shows what I mean by "build quality" with HP Elitebooks.
