Heads

Iam not sure if i should be asking this on these forums, If iam not suppose to please let me know ill remove the topic.

My question is, Is there a place to find out whats the going rates on heads are , Or is that something the players come up with on thier own.

just watch the shops or write a program:
This program should do: you enter e.g. 12000 exp for 2059 geon. then you just calc geon per exp and multiply this with the exp of the other scrolls... and then you'll see whats the best scroll / rate etc xD

Thanks much. I was thinking of writeing up something that would list the going prices of each. But with changes ect in game iam trying to decide if it would be a waste of time. Atm iam in the middle of writeing up a map with monster locations and the monster levels to make it ezer to run though the quests. But then again i am pretty good on remmbering where the mobs are that i've ran into once before but i beleave doing this would help out a bit for thou's who like things to come much easyer then the game lets it be. But anyways thanks for the info
