I've never seen one of these before, so I thought I'd share.
I'm doing 15 stairs in my installation, and I'm thinking this neat little tool could make it a lot easier. It's a digital angle finder for $50, it measures angles and displays them on a little LCD. Kinda like digital calipers, but for angles.. =)
It's available through Princess Auto (Canadian tool/misc retailer). I'd put a link here, but their catalog is a collection of PDFs.
Their site is
www.princessauto.com, and the catalogs are here:

I haven't started my install yet, but like I said I have some stairs and a lot of trim to do. I suspect this could make it a lot less painful.
