Ha! I had an inkling the French DVD might actually end up being cheaper! Makes sense though; it's value priced over there because it was a major theatrical release, no doubt. Over here, or rather in Canada it's more of a specialty title hence it's just more expensive.
I have a region-free player, too, and nearly went for the R2 as well. Chose the Canadian one in the end because I can play it on my Blu-Ray player, which even though it's not a Blu-Ray disc will look as nice as possible on the HDMI connection ;)
