The problem with pens is getting ones which'll write to the CD. Your typical fibre-tip doesn't work properly (the ink just forms into blobs), so you can get special pens for it - check out your nearest computer shop or office supplies place. I'm sure it's all a con and they're just normal pens sold for a higher price with "CD" written on the side of them, but even so it only cost me a few quid for a pack of 4 different colours.

Label gadgets may or may not come with the rewriter - cheaper ones don't. They're only a few quid anyway - computer/office supplies shop again. Label-printing software often comes with the rewriter, or you can get any amount of freeware, or even just clag it together in Word.

Speed-wise, mine works fine (dual-speed write) on a 233 Pentium.

Grab.
