I have a Bachmann 57 602 "Restormel Castle" and it is a very good model. I haven't seen any reviews of the Heljan model, so I'm not sure if they have fixed the overscale width which the 47 suffered with.
The other consideration is the cost. A Bachamann 57 FGW can be bought for £45 the Heljan one is around £63 so you pays your money etc etc..
