Class365

I'm fairly new to the hobby, and one of the main things I noticed when searching for rolling stock is the lack of any AC EMUs. I find this weird considering there are many AC locomotives available, such as the class 86, 87, 90, 91, etc. From what I have seen at various exhibitions I have visited, modelling the west and east coast mainlines in periods after electrification seems to be pretty popular, and there are more and more layouts set in the present day, yet there are no EMUs to operate alongside the various locomotives. I guess you could argue that EMUs don't have as much prestige or interest as locomotives, but there are already a lot of "boring" trains produced, like the many first generation DMUs which seem pretty popular. So I don't understand why there is such a gap in the market as far as AC EMUs are concerned. Is it because companies are too afraid to make the "leap" in case the product fails, or is there another reason?
