Does anyone know any website apart from eBay and other marketplaces to buy old discontinued Sonos Play-1. I already have a Play-1 and recently bought a Beam 2. I would like to pair the existing Play-1 with the Beam to setup surround speakers. Since the old Play-1 and One SL can’t be paired I’m looking to buy the old Play-1. Upgrading to two One SLs would be expensive for me. Any leads on this is much appreciated. Even if someone is willing to sell, happy to make an offer.
