I like the Surveyor's Rod for a lowbie shaman. It's quick and still gives +WIS.
Even though the dmg is only 5, your melee damage is capped at levels that low anyway. The delay of 20 gives you more chances to land hits so I think it turns out to be decent DPS.
If you have the means to obtain it, or if you can find it in the bazaar, the Rune Etched Icewurm Fang is an amazing twink weapon. It has a low delay, high ratio, and a proc at level 35.
