IMO a DVD writer should write CD-R's fine. So if you have space constraints on your PC then stick with a DVD Player.
However, CD writers are extremely cheap, so if you have space internally I'd recommend that you pick one up to install (Of course don't buy any Buslink products!). This will also save wear and tear on your DVD Writer.
But DVD Writer prices are coming down, so that won't be a huge issue in the future...
