why wouldn't somebody just look it up at consumer reports? they just got a court case dismissed on the subject because their methods/proof couldn't be refuted. if it's not accessible for subscribers it's probably referenced all over the place in misc articles anyway (e.g. 'cr hated THIS and loved THIS'). an online subcription is certainly worth considering if decent-dollar purchases (outdoor grills, filters, appliances, etc) are going to be considered in the next year.
