The Bushido's are seriously good. I got 1-9 at the end of last year and there isn't a bad card there. I can't seem to find anywhere that sells the other Bushido's but will check out the HMV site later when I get off work.
bestbuy has Bushido 12 and 13. 12 is $13.99 and 13 is $9.99.
I also checked Walmart's site and they actually had some pride DVD's as well to my surprise. A few of the early Bushido's all under 10 bucks.
