I bought an Autosharp paint touch up pen from Autovisuals.com. This product was mentioned in a previous forum post. You send them your paint code (R44 for my Formula Red) and they send you a pen. The pen was easy to use and the paint was a PERFECT match for my 12 year old car - just amazing! It looked too dark in the applicator but was correct upon application. I filled small and large chips easily. I'm not sure of the long term durability of the pen - I'm concerned that the nib might dry out or the valve become clogged with dry paint but my initial experience was very positive and I reccommend this for small paint touch ups.
