You will not find quality fancies on aquabid or your local chain store. There are some online options if you have the patience to wait for exactly what you are seeking (it may take a year or more) and the budget to afford it.
Dandyorandas has some of the best quality imports available for auction in the US but expect to spend $500+++ (not including overnight shipping) for a show quality import. They previously were affiliated with the Goldfish Connection and there are over 5000 pictures in the GC's gallery if you are interested in seeing what has sold in the past.
Buygoldfishonline has been steadily improving with singular show quality fish limitedly available (same price range). They also sell on EBay from time to time.
Goldfish.net also auctions imports for $125+++(on up plus shipping) but their reputation tends to favor negativity in goldfish circles.
Raingarden sells top quality fish at more reasonable prices/shipping as well but they are US-bred fish. There are also various other private breeders that have fish available from time to time but you will be more likely looking at ungroomed juveniles that require tons of time, growing out and conditioning. Adult fish either will not be for sale or for sale in very high price ranges on very rare occasions (such as a breeder leaving the business).
If your seeking a specific breed, I may be able to help point you in the right direction of a US breeder (no guarentee though!) but if your only seeking imports, your best bet will be Dandyorandas. Hope this helps!
