<P>Anyone have a peak flow meter at home to check your FEV1? The one I saw on Amazon is only about 40 bucks, but I want to know if they are pretty accurate or way off before I buy one. If you blow in your 60s on one, is that about where you would blow in a <NOBR><A class=FAAdLink id=FALINK_3_0_2 href="#">doctor</A></NOBR>'s office or are they 10% off or more? Also, do you need a doctor's prescription?</P>
