I have been trying to get in touch with XS Engineering for quite some time about one of their products (IC core), but I havn't been able to get in touch with them.  The only means of contact I can find is their Ebay account which has been ineffective.  Is there any other way to contact them such as a phone number?   I know they changed their business model recently but I am under teh assumption they are still in business- true story?
