I suppose the hardware is only as good as the burning software you get bundled with the device, John.
These days, CD Writers get bundled with Easy CD Creator, which I think is a load of tosh. I much prefer Nero Burning ROM which is much friendlier, looks better and is easier to use. Very rare, though, to find a burner that comes bundled with it. You take what you get, I suppose.
Anyhoo, as for the burner itself, anything better than an 8x8x32 Drive will more than suffice. One of the Teac machines is what I would recommend, although there are alternatives like Sony and Philips and Yamaha.
Shop around. Try and avoid places like Dixons and Comet and Currys if you can. Bad service and bad advice atop steep prices is all you'll find in these places. Check out your local independent store if you have one. Prices will probably start at around £30 these days, and the blank media is ten-a-penny now - just make sure you get blank CD-R media and not blank audio media. Having ten or twenty blank CD-Rs sitting around is always helpful, and possibly one blank CD-RW (a rewritable one). Audio CD-Rs are only good for copying audio CDs, which we're not allowed to do anyway, are we?
Hope that's been of some help John. Need more info? Then you know where we are!
