I don't know if that is really a rip-off, shipping a frame to Australia really does cost $500. And ebay does a horrible job at estimating shipping. I'm really reluctant to ship anything out of the U.S. unless it's through ebay's global program. I'm sure I'm losing out on some sales, but I know someone who sold something for $400 and ended up paying more than that extra after the fact. So he would have come out ahead to throw it away. Little known bug in the system.
I think I may have bought something from an ebay scammer. Probably have to wait a few more weeks to know for sure. $25 lost is not that big of a deal, but now I'm starting to regret taking a chance.
