I have 3 N.O.S. SIA RTA-420 mics NIB. These are already in USPS flat rate shipping boxes. To my knowledge these are the last available on the planet. Rational is releasing a new mic, which is pretty much the same mic, but with Rational Acoustics branding. dbx sells this mic as the dbx RTA-M. It's a pretty darn good measurement mic for the money. I'm asking $80. each shipped to the USA. If you are farther, talk to me about shipping. You will not be able to find a mic like this for less. I've looked all over. I originally had 27 of these, given away as gifts, etc but have had these 3 for going on 2 years and really need to get rid of them.
