Can anyone recommend a good isolation transformer for sale on-line?
Need one that will handle 5 amps or so at 120VAC, and have a standard AC
plug at the outlet. Prefer one for less than $100 or so, unless that seems
unreasonable. Found one at Mouser for $114 but that's only good for 1.25A.
Getting lots of irrelevant hits on google...

Thanks.

I think the $100 and "good quality" exclude each other for a transformer
that size.

the smaller units as used with cash registers and POS systems tend to max
out at 4 amps.

is used is ok, look for stuff from acme, topaz, oneac, shape, powervar.
powervar even had some interesting ones based off toroidal tranformers if
you want the ooh and aah factor.
