Well seeing as socketing is random with the socket quest, and u only get 1 chance at socketing an item once (no using socket quest on same item more than once) i got lucky on my ezerk last ladder with my socket quest, it got 6, so its all luck i guess. Thats all i can do to help now, cuz i dont know prices on ladder atm.

EDIT:: The number of sockets are random Bob, my friend got 4 from socket quest on ezerk he got from lister...
