I don't know if it really died, but it seems so. Approx. two years ago I was interested in UDM 220V, I waited long, but no news about it, so I just bought a 110V version and a 1000W voltage converter, so I can use it in Europe. I now have it for almost a year and still no news about 220V version yet. So, If my memory serves me well - two years passed, and no news about 220V version, so I'd say the project is kinda dead...
I'd buy Meguiars G220 if I were you, it has a better handle, and is more powerful if I'm correct. Or even better, if you have the money - get a Flex 3401, a way better machine than UDM/PC/G220.
