the big diffrence between arcade and pro is the hdd... and for the console hdd is playing very big role.. haha so if u want all the feature of the cosole the might aswell get the pro.. and if u dont care much bout the feature and just want to play only then get the arcade...

there is a way actually if u dont want 3 rod.. anyway i dont really afraid of 3rod.. its cureable.. but i be more affraid of e74, 1rod.. that one no cure.. hahaha...

if u dont want to get any of this rrod.. but still want to own xb360... then the only way is to buy it and put it in a glass box.. dont even turn it on.. and ur 360 will never touch by rrod problem.

if the above doesnt suit u.. then there is no way to get away from it.. it just matter of time.. ok... just enjoy it once dead send warranties, if u mod then u have to face the consequence la.. kan..
