Purchasing flash 8

Can anyone tell me where I can purchase an inexpensive new/used version of Flash 8? I am on a IMac 10.4.11 which I understand will only take Flash 8. I plan to purchase new IMac in the future but for now I was working on a project in Flash 8 with a demo copy which has expired and I have no way to finish it. I would appreciate any help anyone could give me. Thank you.:confused:

Cheap? Amazon.com has it. Also, hit up eBay - find only unused copies because I don't think Macromedia/Adobe will allow transfers of older application licenses. Not 100% sure about that, but that's the only lead I have.

Thank you.
