My wife and I are in the market for a new TV. We will be watching DVDs, and digital cable. I have been looking at the Toshiba 32af43 and will use component. I did notice that certain people talk about the 32hf72 (last years model). I don't know if I can find this but it does have HD and progressive scan. Is there a noticable difference between progressive scan and component? I understand the concept behind both but we are trying to save money and if the difference is not night and day then I will wait for when we buy our dream tv in 2-3 years. Please advise.
