The issue is that the serious hard work has been done by the Dapol designers; the level of detail is incredible (and much appreciated), yet the results of it are being spoiled by glaringly obvious schoolboy errors and careless assembly. When a full set costs in the region of £230 (from the cheapest box-shifter), I'm not happy to just shrug my shoulders and say "oh well, it's better than what we had before". Perhaps you don't notice the cooler groups from platform level, but in a scale as small as N, you spend far more time as the "eye in the sky", and with the four main types having very obvious differences when it comes to the roof grille/fan arrangement, having Marstons on refurbished powercars just looks ridiculous. It's a hell of a lot more obvious than the angle of the roof, or whatever all the fuss was with the Heljan 33s.
