Unless you
really know what you're doing and what to look for (and look out for), buying a 5oz Engelhard on
ebay is a very dicey proposition. Fakes litter
the landscape and some vendors are reknowned for peddling fakes (yeah--I know--that's a real shock). Unless you're a truly knowledgable buyer with an
experienced eye, your likelihood of getting burned is more than I'd like to face. If you dare, go swimming in that pool at your own risk...
