My vote(s) would go to what I view as the better Lima models such as the 73 and the Class 101 Met-Cam unit, also the class 117/121 DMUs and perhaps the GWR railcars. Not much point in stuff like the 33/26/27 coming out again with Heljan promising them (eventually). Shame about the 31 really, I reckon the body could be as good as the Hornby loco - it certainly looks right from most angles.
