Yeah like the others say im pritty sure it is the same script. just cheaper price.
Personaly i have the RSBots.net version because i trust all of RSBots.net and prefer the name.
Super stable bot and cant go wrong with either one as the price is so worth the bot you get.
i have rsbots script and it works fine for me. never had any problems with it at all
from what i hear, rsbots are quicker at updating their scripts. although i have never tried Kminer
