Here's a link to RiD's website where you can download RiD (includes the free powerminer and many other bots): http://www.robotzindisguise.com/
RiD takes control of your mouse, however, you can set up a virtual machine to run your RiD bot on. I personally don't think it's worth the trouble for just that 260K mining experience.
I'd personally suggest you use "MSI," which is a universal Simba script that does almost every simple thing - from woodcutting to fishing to cooking to mining. However, there are many other scripts in that section which work well. Simba does not take control of your mouse and does not require much time to set up.
