Got all my own tools at home, but father in law has a supply of timber and a table saw, and enough tools to get the job done so I never bother bringing my own unless I’m getting stuck in to something fairly involved.
I picked up one of those Dewalt impact drivers and drill drivers to upgrade some older tools.
Contractor grade tools are pretty affordable when compared to the lightweight carbon junk I buy for my bikes...

Though I assume you don't have one because you're at the in-laws and making do with their stuff?
