After much thought on getting a 2018 MBP, and even ordering a BTO 13” with 16gb RAM, and cancelling after more thought, I picked up a used 2015 15” 2.8GHz integrated graphics in perfect boxed like-new condition (only 13 recycles on the battery) for about $1,000. So, for the prices you’ve mentioned, it seems a bit high, unless you value the option of APPLECARE and a few more years of peace of mind.
One thing mentioned here about potential battery problems sitting being from 2015, is that not all 2015s were made that long ago. Mine was made just this last year at the end of their production. So that and the low recycle rate, I’m not worry about any battery issues.
The 2015 may be ‘old tech,’ but for my use will be fine, much better than the MBP 2011 it replaced. It’s still plenty fast enough unless you are doing high end graphic/video work, and then you just have to decide if your time and computer processing time ratio is to your advantage for the price. The 2018 could be a good choice of course, but for me the advantages of port selection, great keyboard, and still excellent display, outweigh the future worries of the newer models. For the price savings, and for a few more years till Apple fixes the dependability issues and makes a leap in performance... it was a ‘no brainer.’
