I checked out your site and it looks pretty good to me. I think this is a product that has some real potential for profit. My one complaint about your site is that I have a pretty large monitor and all the info for your site was jammed to the left side. It took me forever to read and scroll down the whole homepage. There is a way to make your site adjust to the user's settings automatically which would fill in the whole screen. I am not personally sure how to do this but I do now that it is a farly simple thing to do. I just think it would be more effective and easier to navigate.
