I wanted to expand my system, but not spend too much money…I got two old (series1) Play:1 speakers  from EBay - about £60-70 each.

I was dreading adding them to my system, as I’ve has issues in the past, and with all the recent (and ongoing) app debacle  I feared that installing ‘legacy’  hardware might be a nightmare…

Amazingly it was the easiest install ever!   I had to factory reset one (easy job) - but both of them were added to my system so easily, registered, and joined as a stereo pair.  I’m amazed how straight forwards it was

Honestly, given how rubbish everything has been with Sonos recently this was a breath of fresh air for me.

If you want to expand your system, and do it on the cheap  I can surely recommend this route.
(a new Era100 is £200, and who wants all that ‘Smart’ stuff anyhow eh?)

just wanted to share a positive story!
