there are several Phillips, Marantz, and Pioneer stand alone audio cd recorders available from hi-fi shops which all give excellent results.
They are much better quality than your computer if you only have a basic soundcard, but not as flexible for editing after the recording, since you have to record to re-writable cd, rip to the pc, edit and then re-record on the pc writer, which all takes extra time. But they are all you need if just wanting to store your sequencer creations.
The Philips 775 is a double deck with record and playback decks built in. I have used a Pioneer 509 in the past, and this had a very good recording quality and was highly regarded for the price.
You should buy a copy of What Hi Fi and scour the advertisements for the best prices if you want to go down this route. The discounts vary a lot, particularly if a model has just been replaced.
But for the £250-350 you could get a pc writer and audio quality sound card, only trouble is this would be more fiddly to set up and use maybe? Also you would need an audio recording program on the pc.
