I've got no idea on the actual figures, but the good 'ole A500 must've sold quite well here, as I recall many of my friends having them (most just for games) back in the day.
There was also this towered machine I fiddled with Lemmings on at a girlfriend's friend's house. Turns out it was an A4000T, which I'll bet they just binned

That being said, even my friends that had them look at me like I'm nuts for having Amigas in 2010!
