Just some more info: I considered the new MBP or refurbished 2016-18 from Apple as those prices include VAT which I can claim back (effectively a 18% discount), bringing the price closer to the second hand ebay ones (can't claim VAT on those). The reason I didn't go for the new MBPs is that I can't stand those keyboards, tried them at Apple Stores, several times, tried to like them, but they are just not for me. So, in my head, a 2014-15 is a superior product in the areas I value more (keyboard and ports instead of speed bump and thinness).
But I just realised now (and thus getting cold feet about the MBP) that there was another option to get a top of the line laptop with a good keyboard: 15" Surface Book 2, some reviews call it what the MBP should have been. Yes, of course, it's windows, but the keyboard is one of the best keyboards out there. It also has the plus of tablet mode, which is probably nice for editing in Lightroom in the sofa...
