I too would be happy to have illini07 at my Shabbos table. We might be able to be mekarev him 🙂 About the Kashrus part, I dunno…
(Besides “I can only try”, how can you rely on someones kashrus if you say you may not trust the hashgochos that person uses? That person would’ve been using food with hashgochos you don’t [necessarily] use on all his keilim used for the food he prepares for you.)
