Get the WoW Battlechest first. Don't worry about Wrath of the Lich King till you're level 70.  Get the Battlechest and you'll get one month free time to play. Subscription is about RM105 for 60 days.

Alternatively, you can register for a 10-day trial from the WoW site. I tell you a neat little trick. Register for a normal WoW trial. After 10 days, log in to Account Management with your account details and apply for Burning Crusade 10-day trial. In total you get 20-days free trial =P Use that to decide whether you want to continue playing. WoW isn't a cheap hobby.

Lol? I win for the article lar xD Now no more d =( Quitting WoW anyway, PC can't do anything. 5 FPS in Dalaran with ALL LOWEST, even hack the config file and reduce even more. Pre-WotLK can raid till Eredar Twins, now I do 10-man VoA also lag until my eyes fall out of my head.
