Too bad you are not up in this area. We have some wonderful asian markets in the Seattle area. I just bought a bunch of pre-cut sashimi the other night for dinner. There were ~ 8 pieces in each container and the average price was $3.50 per container. I got some hamachi, maguro, smoked salmon and a really beautiful white tuna that I had never seen before.

We can also buy larger pieces of sashimi grade fish there - like the ahi tuna steaks - to die for - when lightly seared!
