My guess is that most monitors are switchable between 110 and 220 volt so all you'd need would be a new power cable. (or am I thinking of computer power supplies) :-?
Anyway, I'd think shipping would be the killer. I just paid a guy in Germany 35 Euros to ship 2 aminet sets plus one regular aminet disk (total 9 CDs plus packaging). Equals about $42 US or Can$56! He said that was the cheapest shipping rate, but seems awfully pricey to me. I could eat at MacDonalds for 10-12 times for that price. I'd hate to think what a monitor would cost to ship. :-(
