Just FYI - Serellan (of many, MANY mods fame) is currently organising a shipment of official Takedown games from Korea, and is taking orders around the $45 mark over at Pie's (
http://www.piestactics.com/) just check the general discussion forum. Course, I have to pay an extra $15 for shipping to the UK, but oh well.
I'll set about attempting a mac conversion once I've got it and then post a review.
