Actually the GUIs are a little different, I had one auth for some different one because It got banned but it is just a tiny little change with locations.
The GUI is easy changeable with 2 simple .png files.
It's all the same script, sold on different sites with different prices.
I bought the RC Bot from rs2botting.com for 14$ through OneBip, if I would'a bought it from rsbots.net I would have to pay 55$. The price range from site to site is just fuck'd up.
