Musinc System/Radio with good sound for a charity (New Malden KT3)

Our radio was stolen from our charity shop. We'd appreciate one, if you have a spare one. My favourite channel is classic fm. We have licence to play a few channels; classic fm & radio Jackie and some others. As long as I can get a reception on these 2 channels, it will be great. It is a medium size shop. So of it has a descent volume, it will be perfect. Thank you in advance.
