If you are doing SEO, not PPC I would suggest targeting the categories, versus the individual items. If you are ready to mount a "doorway campaign" or information pages campaign, and can handle nearly automatic creation of pages with significant content, go for the less searched terms- which will have less competition. I might even go so far as doing research on model names and or numbers.
