Which hardware to choose for snapcast client?

i try to serve music into 4 Rooms at once, prefferably the same music and in sync. Every room has wifi and a speaker.
My current setup consists of a raspberrypi3 for one room, and a raspberrypi1 with a wifi dongle for the next.

For the remaining 3 rooms i need to choose a hardware which runs snapcast client, has a audio jack (or Bonus: bluetooth :slight_smile: ), and is wifi capable.
Since the local second hand raspberrypi1 prices plus wifi dongle exceed the price of a new raspi3 with onboard wifi, i am looking for a hardware to choose.

Do you have a suggestion?

Best regards
