Love both of these models. Saw them for a long time on Olivias trains but never thought of buying but now they are being commissioned by LTM i've preordered the Sir Peter Hendy and will wait for the Beck one to come back in stock.
I bought the S-Stock model a few months ago and was really impressed by it. Just need LTM and Bachmann to commission the class 378 Overground stock and i'll be happy. Having staff discount though does definitely help with these pricey purchases
