Need caviar help in Scottsdale, AZ

Hello--My husband would really like to try caviar so I've decided to get it for him for his b-day, only problem is it means nothing to me. I would love to get beluga if I could but from what I've read it's illegal for interstate trading since it's so endagered so I can't. I heard that osetra was the second best but there is so many different varieties and colors I don't know where to start. Any help would be greatly appreciated and since it's a gift, there is no $$ limit. Thank you so much!!
