Brand New Potter Wheel (Shimpo Aspire)

Hi,
I got a brand new Shimpo Aspire on Mar 7th (proof of receipt included), but I've changed my mind to purchase their higher-end model.
I originally paid ~$530 including tax and shipping, and I'm only asking $479 (i.e. without tax + shipping).
I've only used the unit three times so far, and the unit is in a great condition (picture included).
If you live near Stanford, I can bring it to you; otherwise, I'm asking you to pick up (I live near Stanford).

Thanks!
