Allied stocks them, and they are 1 mile from my house.

Remember, you DO NOT want to get anywhere near the upper limit of these supplies. The heat gets
to be too great if you get within say 90% of the rated output. Plus, that rating is for "average
AC input", not high line (in the US, the AC wall voltage can vary from 90VAC to about 132VAC).
80% of the stated current is the upper limit you should draw.
