I have a used RZ900 for sale. Bought December 2015. Used it through June 2016 then "upgraded" to a pre/pro setup. This receiver brings the heat as much as my pre/pro unit, and has a good/easy to follow interface.
Anyway, this receiver is in great shape. There are no signs of wear. I can ship or if you're in the San Diego area can pick up.
Asking $1800. I think it's $2500 new. Feel free to make me an offer though. Willing to trade as well.
Thanks y'all!
