Wow, thanks a lot. All I needed was the correct wording/definitions.

Be aware that the term "isolation transformer" can also, depending
on which store or company you ask for one, mean something designed to
plug into a wall socket and let you plug a TV or appliance into it to
power it properly without it actually being connected to the
electrical system. These are usually used in repair work for safety
reasons--they'll give you 120 Volts, but only 1 or 2 Amps instead of
the 15 available (or lurking, waiting for your screwdriver to slip)
from the wall socket.
So, if you say "isolation transformer" and they say "$100" or
thereabouts, that may be why.
