They say they are also easier to be made because cast tooling is expensive, but yet they charge more for the billet wheel. That part I don't understand.

Exactly right on your first comment.
On the subject of the second part: setting up a part to be cast is initially expensive but cheap in the long run if the production numbers are high.
However, thats not to say machining wheels is cheap AT ALL. CNC machines are ridiculously expensive and the cutting bits wear out (and they're not cheap.)
