Done it
Well..... I have got a marker now.
It's second hand and I imported it from the states. The price was so right that I just couldn't resist.
I got the seller to put a little letter in the bow that read to the effect of "thanks for letting me borrow your marker, I am returning it to you, blah blah"
I did this because after my research on the Belgain customs site I found out they can't charge you duties on stuff coming into the country that is already your property !!
So I have an autococker now, that I got at an amazing price and just paid $35 to get it over here (with bottle, barrel, the lot). Only took 7 days to get here.
