I will probably seek it out on that recommendation, yeah. As for Siegfried, I get a lot of my old films from a local university, and they don't have a copy. There's probably an easier way, like Googling, but in the meantime there's a hell of a lot of other amazing filmage to get through.
I watched Infernal Affairs 2 last night, as well. Quality film, worthy sequel to the original with the only major weakness, somewhat unsurprisingly, being that Andy Lau and Tony Leung aren't playing the leads.
Loved the orchestrated earth-air-fire-water assassinations that occur at one stage, followed by the ultimate cheesy nod to American gangster/cop films with Danny Boy played on harmonica!
