Free first class shipping from NY. I've purchased many TBs from him and it comes very fast.
I second that. I recently purchased a new trackball from this seller, and it's the best trackball I've purchased yet. I purchased a previous trackball on eBay from a different seller, and it did not work well.
mobilexny has the best OEM trackballs on eBay.
Thanks xliderider for referring me to this seller.
