ARK on Aqua bid has some whites that he may part with. He gave me one in the last CRS that he shipped me. Excellent person to deal with and very reasonable prices. Go to AAquabid and send him a message. He will reply.
I have also had good experiences dealing with him. I agree that his Goldens are yellow, not Snow white, though.
Send me a pm, and I will give you an address of someone who *probably* has some nice Snow Whites. We aren't supposed to mention specific sellers on here, are we?
