I'll bet that if you open one of RS's power "converters" you'll find
a high current diode rather than a transformer.
I've just started looking for a 1000 Watt (VA) 115v - 115v isolation
transformer and expect to pay from $50-$100. The 1000 Watt RS converter
is $14.95.
Herbach & Rademan, Inc. 401 East Erie Ave. Philadelphia, PA 19134
lists a 500 Watt 230v - 115v step-down transformer in their latest
catalog for about $50. The catalog is home so I can't give you the
exact price. Sorry.
