Can't find one @ £52 but here's one that went for £72 http://tinyurl.com/s3qog
Got my 5.0 DVD on eBay (legit sealed from MB) & intend to get 5.1 there too!
The big clue on that one is "no retail package".
Personally I'm always a bit wary of eBayers who hide their feedback (and who were called Samantha up until they started selling SatNav Disks) but you could always check out their buyers (http://tinyurl.com/mnvab).
My guess is they've got a duplicated DVD
.......and the duplicated ones don't work , right?
Just checked as you sugested, both 6.1's were bought by the same person, gess I'll have to wait for the next one to come along.
How much are they from the dealers?
Are they cheaper from Germany?
