Asda, in the UK (now part of Wallmart) have a whole range of inexpensive boxes. We got a portable CD/Tape/Radio for £19.99, made by 'Pacific', a while back and the quality is good. No mic on this one but they did have ones with a mic. can't remember how much those were. Try searching for a karaoke function as well. May well do just what you need ;-)

While I was posting I looked up Asda web site - Could not find it on there but looked on Tesco as well. Found a Goodmans GPS155R CD Radio Cassette Player with remote control and,
4 Speaker System.
MW / FM Stereo Analogue Tuner.
Top Loading CD Player.
Repeat 1 / All.
Track Skip And Search Functions.
16 Track Programmable Auto Stop Cassette.
Voice Recording Via Internal Condenser Microphone.
Headphone Socket.

Cost in UKP - £35.99

It is a portable. Would that do? Go to tesco.co.uk/electrical to see. I know it is UK but surely things are cheaper in the US aren't they?

Cheers
