I bought the 512Gb OLED, and within two months decided I needed to upgrade the storage. I replaced the drive with a 2Tb drive, and I’m much happier. That said, I download a ton of stuff and keep it on there. I don’t often play a single game straight through, so I like having the ability to have a wide variety at any given time. Replacing the drive is trivial if you’re handy at all.

I would buy direct, I wouldn’t trust getting something second hand. I’m sure plenty of people are selling their LCD for an OLED, but I would rather go direct unless you’re getting an amazing deal and have some level of purchase protection.
