Easy to see a 'better' choice with the retrospectoscope but Im not sure that a rerun of A class would be as viable as your hink as least this soon. I, for one have multiples of most and would not be in the market for any more renumbers unless there was something new, and there was not that much that was not covered with the A class as far as I can see.I do like the Arrows, though I would prefer to see an earlier era railcar, which in light of this update seems unlikely, unless the internal working electronic etc made that viable.
So oddly, I had intended to purchase several of the then including the RTE Music week sound fitted, which is alluring for an sentimental ex-pat. Funds were then diverted elsewhere, then they were 'sold out', so least I have the option to purchase one (or two ) again now.
