The murals are £25 and the domes are £99.00, for the insides you can use any Rowe Ami jukebox from the R82 model upwards, 1980s jukeboxes onwards. Vinyl but i think the Rowe Ami cd ones would work as well.
I have also used rowe ami hideaway jukeboxes.
I was going to fit a mp3 player in one as well as the vinyl mech, i found a place in USA where you just connect this interface box to your CCC and you can select tracks from your mp3 player.
