....yes just like that one, but after having a good smooch around they are mostly 'out of stock' or in the above case for a 6250 (which in fairness might be the same as the 6310i's connector), or once clicked on a link via googoo comes up with other accessories, but not the one proffered I have found one on a German website and will give them a shout next week hopefully.
The link I posted shows in stock and allows purchase. Are you saying that after paying they say it isn't actually in stock?
