Thank you Meka for your suggestions to buy wacom. but i can't afford cintiq...yet. Besides, i don't have any more place to put it in my room.
Bamboo fun medium could be an alternative for my start. when my drawing skills is on top, i will sell my drawing tablet and also my drawings to my friends until i can buy a better one.
i'm so poor and pitiful right now, mate -__-"
but thanks again for the suggestions, it's really helpful. ^_^
But still, i hope i can buy Intuos 4 or 5 or maybe a cintiq 12wx/21ux/24hd. So, Dear God...(pray that hopefully it all become true)
