Those transformers you found certainly are well priced !
Yes, they're pretty reasonable... and now I notice that they come in an even smaller size!

13 mA @6V, with the same 22mm x 23 mm footprint as the others, but only 12mm high! With a SMD rectifier, regulator, and caps, it's probably not much bigger than a xformerless supply with it's big cap, MOV, and all the
rest.
I'm sure it's still a little more expensive. But maybe not much...

Regarding the PIR sensors ...WOW and they do what they do at such a low voltage too ...awesome!
Those are cute, aren't they? And tiny! I'm starting to use them around the house to turn LED "night lights" on and off. When I stumble into the bathroom at night there's enough lumens to find my target without having to fumble for a light switch.
