That's quite a list of conflicting requirements that you have. If you want to watch DVDs and camcorder recordings at anything like decent resolutions you will need a 17" screen and that is not really compatible with being really light or really cheap. I would suggest that you go to the Toshiba site click here and click on Help me Choose my Laptop and that will give you a guide as to what is right for you. Once you have decided on your spec. then you can start to look at different manufacturers with that spec and work out the best deal for you.
