go to rsbots.net and check out all their bots. they all cost money but are definately worth it. low ban rates, very humanlike, etc.
i personally would get the AutoSuperheat Pro. i used it from 45-98 mage and it is very stable.
If you want some free bots look at Powerbot.org and Rsbuddy. just be careful because the staff is very corrupt at powerbot.
