I use a MBP "Core i7" 2.5 15" Mid-2015 (DG) MJLT2LL/A. Bought it used in 2016 for $1,900. This model. 16gb RAM, 512 SSD It's plenty fast enough for me (god bless SSDs). I don't do a lot of processor-intense work. I'm a writer, and need the 15" real estate (so no downgrade to MBA for me). I've got some money to spend now, and it's a good point in lifecycle to upgrade. But new prices are crazy. Was considering refurbs (e.g. this), but it's a pretty old model, and still not cheap despite serious markdown, and actually specs worse than my current, older, computer (on left below). So what's my bang-for-buck option with 15" screen and 16gb RAM, 512 SSD? FWIW I've got several external USB drives and dock at home to an Apple Cinema Display.
