My personal MBP has been chugging along. It's a late 2011 15" MBP, I swapped out the RAM and put in 16GB and I also have a 512GB SSD. And it keeps up with several of my co-workers devices, the only real issue I have with it is the Graphics Card, but it's not like I'm playing all day or anything. The only issue I've had, was when I had send it to Apple for a Logic Board issue; my MPB was a 2.8ghz i7, when they returned it after repairs it was a 2.2ghz. When you go to purchase a mac, that extra procesing speed is hundred of dollars. But after complaining the credit card charges were dropped and my repairs were free. (Even if I'm sure it cost them next to nothing to do the repairs.)

But I'm more than ready for an upgrade, I've actually bought a few Refurbished Mac's in the past and they've always seemed to be a good price for exactly what I needed.
