Well, I'll give you a quick example - there is a Tom Anderson Drop Top Classic in a shop in Texas (immaculate, but second hand) for $1899USD - that's $2500 AUD - say $400 in postage (seriously!!), add 5%duty and 10% GST and you come to $3335AUD for a guitar that currently retails (assuming you can find one!) for $7000AUD!
You can apply exactly the same logic to
PRS guitars and come out considerably ahead.
Probably doesn't work for Ibanez Artcores though.........
