I didn't see any PAL versions of it back in those days. I saw second hand versions of them in NTSC at shops like EB Games. Either way, that's just trivial information, the real information I'm looking for is why they are so cheap from that eBay store.
And, wouldn't white show dust and finger prints more than black? Either way I think you probably just have grubby hands and don't know how to keep the dust off it (i.e. by cleaning it every now and then).
