Stand alone TWebBrowser like compoonent on Delphi 2010

Hello, We need alternative component to TWebBrowser or you can modify TWebBrowser to fit our requirements. The component should be able to display HTML, CSS and run JavaScript. The component should not use any installed software in OS (IE for example). If you need to install anything, it should be done automatically. The fewer questions will be asked the better it is. IMPORTANT: All this operations MUST be done under user privileges. Two possible solutions we know so far: Google Frame or Firefox pluging. The first solution has a problem - user is asked to install 3rd party program and download over 175mb from the web. The second solution is simply outdated. If you have any idea how to attach Google Frame or IE8 components to our program (without separate installation) then such solution is also acceptable (the user should not download anything from the web). If you know any ready commercial component which fits our requirements - we could buy it (of course for reasonable price only). Even if that is not your component, you will still get you commission - for your help ;) Waiting for your bids p.s. The price per solution is 100-200 USD, as for ready commercial component 300-500 USD.
