I said it in another thread, but it worked for me so I'll mention it again: check out certified pre-owned laptops from IBM. You can google "IBM certified pre-owned" to see what they have.

I heard about this from a friend who works for IBM, so I was able to get an extra percentage off because of him, but anyone can buy the stuff. On top of that, I think they may have made a mistake and sent me a unit with a Retina display. I got a 15" 2012 MacBook Pro with an SSD (I forget the size) for $760, and I've been using it for nearly 2 years now. I put Parallels on it with Windows 10 and use it for URC stuff all the time, as well as Crestron, Lutron and pretty much whatever else requires Windows.

They have a bunch of stuff on there, so I think it's worth checking out. I didn't want to buy new because it *is* a field computer and things do happen. I am super careful with this thing though, since it's much nicer than what thought I'd end up with.
