Well, it all depends on how much we want to invest in those tourneys !
For instance I was refering to my own item stock (3 forces Qs/hunter/shaman and 1 kevlar lax), that's like from 10k to 30k. I wouldn't like to give those as random prices for little tourneys ;p

Maybe we could make a 1tc to 2k items for 2nd place, and 2k to 5k items for 1st. I'm not sure about how rich/poor we are so I really don't know !
