I posted in another thread (probably the Purolator/China one) that I bought some PF457G equivalents for my Cobalt a couple of weeks ago, some Napa Golds that cost about $8 after the local 20% bag sale my store was having and some Purolator Pure One's at Farm & Fleet that came out to $6 after the rebate.
Napa Gold, in this particular application, made in South Korea.
Pure One, again this application, made in USA.
