Tamiya primer is almost completely absent now in the US. I even tried to order more from LuckyModel Hong Kong, and I received an email stating that it's "dangerous material" and they couldn't ship it to me in the US. Even though they did about two months back. I guess the other paints were fine to send, just not the Primary.

IMO, nothing beats Tamiya primer. It is really really fine straight out of the spray can. It's really amazing stuff. Vallejo is what i'm going with now too. It's good, but it takes longer to dry and I have little patience. haha
