If you don't want to be breathing cement fiber siding sawdust, you need this tool. I paid over $200 for it when I bought it new and it has been used to do the siding on one house and one detached garage. It works great with no issues that I'm aware of. I'm asking $75 cash only.
I'm familiar with all the current craigslist scams so don't bother.
