In general, would you consider buying used power tools if the usage is for
one project and after that would be rare and occasional use?

By means of used tools I mean something that is previously used and "look"
beat up like those people sell on ebay. I don't mean original manufacturer
reconditioned tools.

What are some pros and cons? To me if it's cordless I am worried about the
battery.

And if you would consider it, what would a reasonable price point be? I
have seen a new tool with free shipping on Amazon for $150.00 and someone is
offering an equivalent tool that is all beat up with no battery no case no
manual and it went to $79 with $30 shipping seems totally out of line to me.
