that all depends... how long is a piece of string?
never mind crushers. sometimes when he speaks, i'm embarrassed to be canadian.
later years are better IMHO, up to '84 you can import into the US.
good 40 series (the only ones i know anything about) go for $500 for a rat bag to $15k plus for a fawked over one, camping gear, crappy paint jobs, etc...
i'd say the average price for a decent one is around 7-8k. you may find one for less, most likely more. overseas buyers are driving the prices up
buying on the web is hit and miss, you won't really know untill you see the truck in person.
why don't you buy one state side, let someone else deal with the headache of importing? sure, you'll pay more, but you might get to see it before you buy.
older cruisers will be well used, high milers will need work. the quality for the price of used cars down under is not what you are used too.
