I'm not a big fan of wiki's - I find them extremely hard to search.
Although I have eventually found something on one at http://elinux.org/RPi_VerifiedPeriphera ... VGA_Cables
which says they may take a higher current. However it points to lots of amazon links and does not say if they are recommended or not. (all more expensive than the ebay one BTW.)
I wonder if anyone has got one and added an external 5v supply to it?
