inna OP
Yes sure, I would prefer used Antillion. Most used Gryphons that I see are in Europe or Asia, different voltage.
Have a look at the double click magnified shot of the back of this one for sale, sure looks to me they are changeable, maybe inside on the transformer’s primary winding’s, if not switched from 100-120v to 200-240v otherwise this normally isn’t put on the back like that.

Looking at the amount of transformer wires at the back of this pic, I’d say primaries could be rewired for 110v

But I’m sure you’ll find one eventually in the US, we’ve had two in Australia on SNA in the last 6mts for sale used, and we’ve only got 20 Mick Dundee type jackaroos 4 dogs and 50 million kangaroos, 1 billion crocks, oh did I mention White Pointers? yeah we got a few of them too.
