Not sure if you're familiar with UserTesting.com, but their "Peek" service offers 3 free videos of people browsing your site. I use it when launching a new site to see if there are any usability errors I may have missed. Your site displayed and functioned perfectly for me, but you still might be able to get some mileage out of free user videos.

Also, we've been getting a lot of use out of the free SumoMe App on homemadetools.net recently.
