Every exchange as far as I can tell is a little shaky for one reason or another.  For instance btc-e is in Russia or something.  I'd love a site that is clear, easy to use, and there was some assurance that everything was legit so if it went under you could get something back.  Gox was big but so shady about where all the funds were.  See it's weird, the thing that would make an exchange reputable is if there was some big entity backing it, but that also goes against Bitcoin's principles.
