New Price. And free shipping to CONUS.
Count 'em: two controllers, three receivers--making up your quintet--and two sealed replacement batteries as a bonus, worth $40. One new set, with one receiver and one controller, will set you back $470 on Amazon.
Two complete Duet rigs, but with an extra receiver. I had tunes streaming from my computer to three rooms. Shweet.
Everything in excellent working and cosmetic condition, aside from minor signs of wear on the backs of the controllers from slipping them into and out of the charging cradles. You get everything you see in the photo, as well as a copy of the manual.
I'll add that the controller, in feel and function, is one of the nicest handhelds I've come across. You can do everything easily with one hand, leaving the other free to lift that frosty mug to your lips while you're changing tunes.
