If you can wire any of your Sonos speakers you might be able to get by without the Bridge or Boost, that should be tried if possible.
Only then you might think about a replacement. Consider getting a Play 1 or One instead of a Boost, nearly as good for SonosNet (a bit less noise rejection I think) and for a few bucks more than a Boost you end up with another speaker.
