uses?

I've been looking at the idea of getting a mini excavator but I wanted to know what everyone all uses their exc for? I was really looking at a KX121-3 kubota

I want to know the off things people use them for, not digging holes, I know there are endless attachments to use on them. before I got in to one I want to know every single think I could use this for to make it worth every penny to own because I'm not getting one to have as a toy I'm getting one to make money.

thanks
