Hiya (1st post)!
Those ebay 'Sony' sticks are definitely fake. It normally does not matter if they are UK sellers or HK sellers, since the UK sellers get their supplies from China/HK anyway.
Fake does not necessarily make it a "bad" thing though. I have ordered and received one of these sticks from a UK seller and currently it is as good if not better than a genuine Sony stick. Faster and slightly more storage.
Anway, if you are looking for memory sticks I advise you to get a Sandisk one.
Speedwise from fastest to slowest it goes:
Sandisk Extreme
Sandisk Ultra
Sandisk Standard
Sony High Speed (Fake - in my case)
Sony High Speed (Real)
Sony Regular
There have been some horror stories about people faking lower size sticks as the 2GB one, but usually if the ebay seller has good feedback for the sticks then they would be "real 2GB", but still usually fake Sony, if total incl P&P is less than £50.
Hope that clears it up. Check out this link for more info

As far as I know Sandisks aren't as oftenly faked.
Don't let Sony fool you that their products are better than others. Sandisk codeveloped the MS standard with Sony. I advise you to get Sandisks if possible.
