Searching for gen 3 distribution carts

[olsencollects]

Hi everyone, new here - but thought i'd make a post about something which is a grail of mine. Gen 3 is my favourite generation, and I have a goal to acquire all the gen 3 event distribution carts. I am very much aware that these can be easily faked, however I know the ways to tell the authentic copies, based on various data on the cartridge when delving into it in depth. This would only apply to loose carts however, and the easiest way of verifying legitimacy from the get-go is finding the carts which are still security taped to the original gba console. Those would be my preferred option, but I am keen to know of anyone with any for sale at all. Anyone who could help point me in the right direction would be greatly appreciated. Even if its just by letting me know of any out there which you're aware of, I know a few sold on ebay a few years ago which were authentic and still sealed to the gba console. Thanks everyone, please help make my dreams to own these items come true!
