I think my favorite non-sparkcash item would be the Casha's Claw 2h weapon. I love big swords. Altho, I think the armor set that I saw one of the newb fighter GM's wearing one day looked pretty awesome.
My favorite sparkcash item would be my otter. *huggles* The mini-reaper is a close second, especially since he giggles before he tries to murder you. Adorable.
