Don't know if you are hobby type or pro, but if hobby, how often do you really need a mic that is larger than 1". I have lots of hi quality measuring tools and gladly pay the price for swiss made DTI but over 1" I rarely use so I have cheap Chinese stuff. Put that money towards other tooling that is of frequent use. That whole lot might bring 5 or 600 if parted out on ebay and you excepted returns, if not, looks like a pile of used stuff that you likely don't need.
