That's the conundrum of 2 rail O scale. Quantity seems to overrule quality. Pennsy steam is that way. For such a "popular" road with a supposedly saturated O scale following I NEVER see anything other than a few PSC K4s or Westside J's or H6sbs for sale in 2 rail. Where did all the rest of the 2 rail PRR steam go?
The -40-2 is arguably one of the best modern locomotives ever made but has seemingly a small following in O scale. Too "pedestrian" maybe?
At the same time E and F units are done again and again and again in seemingly endless variations, ad nauseam. They must have buyers or they wouldn't be made.
For a model railroader, E and F units span the period from steam into full dieselization. Thus they allow a lot of flexibility in settings and acquisition of motive power. SD-40-2's are restricted to just the modern era.
