I have been buying several Tartan Asia Extreme discs off of eBay. Quite a bit cheaper than I seem to be able to find them for elsewhere, and no problems so far.

Tartan is a video release company that specializes in modern extreme Asian films. You're not going to find Dr. Lamb on one of their DVDs, but movies like Battle Royale are right up their ally. I bought their Oldboy release; not shaby.

Here's a list of the Asian films they've released to date: (from imdb)

• Acacia

• Audition
• Bad Guy
• Bangkok Dangerous
• Bangkok Haunted

I think it must be a Scotish company, not just because it is called Tartan, but since I have been living in Scotland I see them everywhere. And I had never heard of them before.

Tartan Films, established in 1982[1], is a United Kingdom-based film distributor. It also owns the United States-based Tartan U.S.A. and Tartan Video. They are known for distributing Asian films, especially those in the horror and thriller genre, under their banner Tartan Asia Extreme and also, more recently, they have gained a reputation for releasing horror movies of other origin under their new brand, Tartan Terror. Such films include Battle Royale, the Whispering Corridors trilogy, A Tale of Two Sisters, Triad Election (aka Election 2 ), and Oldboy.

i saw tartan videos for sale in a US electronics store once (cant remember the name) but i've never seen them in Canada - other than the used DVD stores.
I grab them whenever i see them.
