I've been extremely happy with my Innuos Zen Mk3. The Sense app for playing music is fantastic. In fact, I know several dealers who consider Sense to be the best streaming app currently available, preferring it over Roon (and others) based on sound quality and stability.
If you need to store some music files in addition to streaming, then consider the Zen (new) or the Zenith (used). If you don't need server storage, then consider the Pulse (or increase your budget and get a Pulsar).
Good luck!
