the phone number
858-864-3029 gets far more search results then the name.
it is/was also called themodchip.com

it looks like it will take about a month to get your product. More then likely its just some guy selling things out of his basement. he gets your order, then places his order with his contact, because hes cheap, he doesnt use overnight shipping services, so when he finally gets it two weeks later, he sends it out.
