I buy most of mine online but if you want to buy 
them in person, i'd suggest Animate world, Little 
Tokyo's Kinokuniya ..hmm.and i think theres an 
anime store in Torrance. However, if you are 
going to AX, I'd suggest you wait till then 
because many many dealers (I like Animate USA's 
boards) will sell boards there and theres no tax
