From Ted Pella you want the "Single Edge, PTFE-Coated, Stainless Steel Blades," product #121-3. These are great blades, very sharp, although they can be a little harsh for the first couple of shaves.
House brand blades are available from CVS and Rite-Aid drugstores. Just be aware that these are carbon steel and must be removed from the razor and dried immediately after shaving, otherwise they will rust in an amazingly short time.
