It's still available for sale in the Line 6 Online Store:

Unfortunately they only ship to the USA. When I was trying to get one a few months ago, I called up Line 6 to ask about this, and the support staff suggested looking to eBay, getting an American friend to buy one on my behalf, etc. I eventually found a used one from this forum, so you might try that as well.
