Tony,
I had no idea you could power that many buildings with just 2 of their power supplies. That's good info. I do have their accessory packs of cords as I've used them for my holiday displays with Lemax/Dept. 56. They add a lot of flexibility for connecting a group of buildings like you say. I have some of the buck converter parts but haven't tried them yet -- got parts list and diagrams from this forum a while back -- I know they will work. I like the idea of running them through a fixed train transformer like all of my accessories. I plan to do the same thing with Woodland Scenics buildings. I find it satisfying to have all of my accessories running through my main transformers -- reduces the amount of outlets needed. And then it's easier to turn the layout on and off at one central location -- as Mike is trying to do.
