Hi Steve,
Sorry to hear that - your kids must have been pretty disappointed.
We (well Christian) bought about half a dozen when we were over in May & they were all pretty good - a couple had greek subtitles on them - but you could chose to see that in a positive light & say it was educational

There were several guys selling them when we were around so it could be that some are perhaps less circumspect than others?
Anyway, it wasn't very nice for your children - I do sympathise.
I doubt I would buy for myself, I think I'd leave it to Christian as he can be a mean 'haggler' when the occasion demands it!
