Well the 2nd chance offer IS through eBay and seems legit.

SOoooo...my next question..

Are those rims really WORTH almost $200 w/shipping???

I thought my NOS Regina 5 speed freewheel for $125 was kind of ridiculous, but this....

I did what CadilacMike said, and sent a counter "offer". The amount being my bid BEFORE I upped it to $151.
For $186, I'll have to sleep on it. (with my fingers crossed)

Anyway, thanks to all for the insightful replies!!
At least now I don't feel "scammed", just bewildered.
