Tribot is definitely worth it. I paid $6.50 about a week ago for 30 days of Tribot VIP, and there are literally heaps upon heaps of free scripts, and also quite a list of "Premium Scripts", which you have to pay extra for. Definitely worth $6.50, considering a mil is about $5, and you can make a mil in a day or even within hours using some of the free scripts on the forums.
