Just picked up my pre-order of the BTK, BCK, SK and FK, and am delighted with them. The ride height is slightly low, but only by 0.5 mil or so - easily fixable if I decide it's worth it. The moulded details look fine and make the coaches much less vulnerable to breakage than some recent releases. The general finish is superb. Quite expensive at c£48, but for anyone modelling the 50s ER absolutely essential.
