How important are metatags for seo?

Just spent a couple of hours sorting out the meta tags for a client and thought I better share the reasoning and detail. Meta tags or in full, Meta Description Tags are not that important for SEO purposes, but as everyone knows, rankings don't necessarily convert in to sales. These meta tags are simply the short paragraphs describing the page content, and thus a good one will lead through to greater click through's. If you do not set them up through your cms system then Google or equivalent will simply pluck text from the page it deems most relevant, to the search being conducted and the page, and this may or may not be relevant to the true search.

The description should be between 150 and 160 characters long, spelling and grammar should be correct! It will take you a while but once done you can tick it off the list of things to check off!
