RuneDream (Super new, limited features, but eh it works)
RiD (costs $, limited selection of scripts, I hear all kinda of mixed reviews about it)
Scar/Simba (I'm a Simba guy so I'm going to be biased

It's free, open source, you can learn to script and write your own scripts for it, large helpful community, etc etc. You can also check out the scripting video tutorial links in my sig)
As for bans, meh Jagex sucks at catching botters, I can assure almost all Simba/SCAR scripts are safe, can't really speak for Rid I've never used it bit it's widely used and seems safe, RuneDream SHOULD be ok, but it's way too new to know.
Simba is a bit harder to setup, but anyone with half a brain and a bit of patience can do it, there are step by step guides.
Don't need to k now how to code at all to use it. But we have TONS of learning to code tutorials, and if you do learn to code then 1) You can access the SRL member scripts (better scripts kept here) and 2) Write your own scripts!
