I bought them from my mechanic, here in Canada. He got me a pretty good price on them. I paid about $550 CDN for the pair and they came with new Bosch corner lights as well - the dark orange euro style ones. Since I have the newer clear/orange corner lights already, I sold the orange euro corner lights on e-bay and made some money back.
They also came with the 6-pin wire connector required to attach the lights (the US version has a 5-pin connector). There are some excellent posts here detailing how to connect them and the part numbers required. It's an easy swap.
There are also some good sources for lights here on the board - perhaps someone else can chime in? I think there is a company called Puma Products or something that offers Hella euros ata good price...try the search...
