I received a call from a local shop. They have a 2015 15" 2.8 Ghz 256 GB for $1,100 and a 512 GB for $1,200. There's a Craigslist locally for a 2015 15" 2.8 Ghz for $1,100 but it doesn't specify the amount of storage but I think that it's 1TB given the original price that the owner listed. It some scratches and a small chunk of aluminum missing. The local shop only sent me an email on Friday while I was looking at an iMac 27 inch with 256 GB or 512 GB of storage. Decisions, decisions. If I got one of the 2015s, I'd either upgrade it to 1 or 2 TBs. I don't think that I could do that with the iMac internally. I had seen several other 2.8 Ghz/AMD models but they all sold off. Add to that the possibility of a 2019 16.5 or 17 inch MBP at WWDC and there are a lot of choices out there.
