Portable system with DAB, CD, FM, cassette rec/play and internal mic?

I bought a Goodmans GPS285DAB portable system as a gift to my wife some months ago and she has only just tried to record to the cassette recorder. We are VERY disappointed with the playback quality from the cassette recorder from any of the sources, internal microphone, CD, DAB, etc. The background noise is appallingly high, with rhythmic thumping noises and hiss, sounding much like DC recording bias and permanent magnet erase have been used, or the tape head is badly magnetised. I have tried using two types of ordinary ferric tape - no difference. I have demagnetised the head, but no change. I did a search on the internet and found an Amazon review of this machine from another disgruntled owner who said the recorded quality was "c**p". This owner obtained a replacement which was the same, so I reckon the basic design is at fault. Unusual for Goodmans, but I suppose you get what you pay for. I am planning to return it to the supplier for a refund, but will need a replacement.
Does anyone know of a good complete system, with the same facilities, (internal mic or mic/aux input is a must) for under £200. I know I can get separates, but these will work out much more expensive and linked-together separates are not easy to carry around the house. Any suggestions will be welcomed.
