Another vote for Nashbar tape. Same stuff is also sold by eBay seller Abaxo. Inexpensive, comes in lots of colors, works great when hot, cold or wet. Have had white, red, black, blue, brown on many bikes for as long as 8 years without having to re-wrap. The white is easy to clean, doesn't stain easily.

Have a couple bikes with Sella San Marco leather tape, supposed to match the Concor saddles. Nice, especially when wrapped over a layer of Nashbar, but after a few years the upper colored layer starts to wear off.

Have also used the Selle Italia leather Smootape, which feels nice but bleeds color into my gloves and stains my palms when wet or sweaty.

Just wrapped the Zunow with Cinelli Calaido (sp?)black tape; top Fizik-like layer is perforated to show the colorful speckeled underlayer, so a little thicker than Fizik. We'll see how that works out, and it also comes in white.
