Treated or regular lumber?

In my area I've seen many basement where steel studs were used.

Bingo! Do like the commercial builders do and use metal studs, or a smaller metal furring channel fastened directly to the block wall.

Also, if you have a concern about moisture, address that rather than building to accomodate the water. You would be much better off sealing the space from water [liquid or vapor] than planning for wet building materials.

Whether someone has moisture problems or not, direct contact with concrete requires PT wood.

That's always been my understanding too... I've decided I'll just go with the treated & not worry about it.

From what I remember around here, vapor barrier is required between masonry and wood no matter what type of wood.
