Recently ordered the above on the US/GERMAN cd wow site. www.cd-wow.net Paid $77.95 which works out as around £40 after conversion. This is £10 cheaper than the UK site!
Jian - They have recently released the tin box set! You can get this from play.com or use my method from the cd-wow.net site. I would go for R1 for DTS sound as others have stated on this thread!
Custom charges vary wildly and there doesn't seem to be any consistency at all. But as a guide, the last similar item I bought was the Shield S2 which is a 5 disc set and therefore smaller than a tin set you're after, and I paid just under a tenner customs charge.
