Ideally you'd want a new PSU (really don't want to pay to ship that thing anyway, especially since it's useless over here).
What do you want to use it for? If you're just playing old floppies, and your TV won't display PAL properly, it's nothing to hold down both mouse buttons on startup, hit the space bar (goes to NTSC) and select NTSC bootup.
No problem at all if you're using an old C= monitor.
Might be a slight hassle, but NTSC A600s are pretty rare.
