I appreciate your comment. However, I am having a little trouble understanding it. I personally find my design easier to navigate than Craigslist and less crowded. I understand this isn't the case for you, and I would really like to hear more detail about this.<p>As far as filtering, you're absolutely right. I wanted to include a sort of advanced search that constantly narrowed down the options using AJAX as you selected things, but it proved too difficult to implement and I settled for second-best.
