I am on a Surface Pro 4 now, which I bought used on Craigslist in late 2016. I'd highly recommend checking Craigslist often to see what's out there. I got the tablet (64g), keyboard cover, leather case, screen protector, pen, charger, and a carrying briefcase for $725. It was easily worth twice that, and I love it. I carry it in my purse to depositions and have it hooked up to two monitors at home to work remotely. I had a brief issue with it a few weeks ago where the screen would stick/blink but I think it may have been a reheating issue. I totally powered down, left it that way overnight, and haven't had any issues since. Use it almost daily for several hours at a time with no issues, have used it with a remote server, as a gamecube/wii emulator, and using light Steam games.
