That's the trouble with globalisation (or expensive shipping) You pay peanuts for internal US delivery and in Aussie we are up for about $70 to get a keyboard from the USA. At least we have one advantage over Europe - they don't stick us for duties and if you get caught for Tax - its only 10%.
Funnily enough I have ordered lots of things from overseas, but never had to pay duties so far... touch wood (hand on head).
Having said that I must not be only person to notice that on eBay especially they seem to have gone crazy with the amount they expect for postage/shipping, in fact so much that it puts me off bidding.
Funnily enough a few weeks ago I was looking around to buy some new earpads for my Sennheiser HD650 headphones and in the UK the very minimum I could find them for was £49.50, which is about $77 US. Considering that they happen to be made from cheap upholstery foam with a tiny piece of cloth and a couple of small plastic parts and that all compression welded automatically in a machine - I feel the price they want is absolutely ridiculous and even more so considering that the same set of pads is shared by much cheaper headphones. Now if I used my fingers and trawled the net I could buy them for $55, but with $20 for shipping that made them almost the same as buying in the UK... my answer was I made my own and paid nobody nothing because when I bought my HD650's I seem to recall replacement pads cost about £10 which is about $15.55 and a price that sounds just about right considering what they are made from and the skill required making them.
Sorry that wasn't about keyboards, but shipping costs have grown stupid these past few years.
