SO had a decent pair of flat BMX pedals with pins on his bike while he waited for eggbeaters to come in. I can't remember the brand, but they were around $50 or so. I like the BMX style for casual biking because they're nice and solid under your foot and your shoes don't slip. Basically anything that's metal and around $30-50 would be fine for casual biking, I imagine. No need to go all out since he only rides a couple of times per year.
