Questions from newbie  

I have been looking at some HDTV's for a while. It is a large investment so I am looking for some info on which to buy. The best picture I have seen in store has been the 16-9 50in Toshibia. They are getting a 55in 16-9 in soon, is bigger always better. Will I hate my 16-9 while watching regular TV? Is there a faq somewhere that I can look at to make sure I am getting all the features I need for the future. If not which features do you believe are mandatory. Which is considered the best HDTV bang for the buck. Thanks for helping a newbie.
