The Radio Shack 25 amp supply, which someone else mentioned and recommended
is available on the website, but the local store nearby told me they will
order it for you (at that sale price--$59), and no shipping cost.  Most
Radio Shack stores have stopped stocking those power supplies locally.  I
already had one, and the Samlex 1223 also, and both work pretty well.  By
the way, I did pull the cover off both, and they are not the same--they just
looked very similar.  Actually, the Radio Shack supply looks like it might
be a tad more substantial.  Anyway, for under $60, it's possibly worth a
look.
