I got a MacBook pro 2013 15” max spec 16gb/nvidia gpu. 430 cycles (not a lot) and if it needs replacing Mac store will do it not that expensively. I paid 900$ u.s. on eBay. Model had a bit of scratches but who cares made it way cheaper . OP just buy a refurbished max spec 2013/2014 15” off eBay .
Only gripe I have is that it sometimes doesn’t ground well with the unibody casing
