I really like this site. It's clean sharp and really sells itself without overdoing it. The only thing I would change if anything at all would be the topline nav. I would style it to be a bit more consistent with the other nav blocks, even if you keep the different mouse over highlight colours. The only other bit of advise would be to obfuscate your email address under the 'contact us' button. Using a mailto is just an open invitation to spammers to fill you inbox.
Good stuff.
