Every week a Guardian Money reader submits a question, and it’s up to you to help him or her out – a selection of the best answers will appear in next Saturday’s paper.

This week’s question:

I need to get a new music system – I want a turntable, CD player and, ideally, an iPhone dock. I’m hoping to spend less than £300. Should I buy second-hand? Which models are best? If new, who should I go to? Friends have suggested Richer Sounds.

What do you think?
