How much do bench skills matter for a postdoc?

If you're hiring a postdoc, how much do you care about the techniques they've used in the PhD?

I'm thinking ahead to the postdoc search (will probably start in earnest in summer/fall). My current field is a somewhat obscure area of human molecular genetics, lots of old-school techniques. I'm very interested in moving to a model organism that will provide quick output during the postdoc and let me transition to a career at a primarily undergraduate institution. I've also had very little opportunity for bioinformatics training, which I would like to learn. (I see lots of online ads for postdocs listing a slew of particular skills, but I've heard these are less common paths compared to personal networks so I'm wondering if they're representative.)
