Edit: I had a senior moment. 24 volt RMS AC is equivalent power-wise to 24 volt DC. Doh! If you can find a 120-24 volt xfmr with the proper capacity, you will be okay.
Now, if you are thinking about DC, you may find a PS as cheap as a 24 volt xfmr. I found a neat little 24 volt DC 2.5 amp power supply for $39:

Another for $37, Din rail mount, 2.5 amps - very neat! - Would go great inside a control cabinet.

Another little unit, $32. PST-AC2425 2.5 amps

There may even be some cheaper ones too. This was just a quick search on google.
