$400 to $450 is a 50% increase? Or are you talking about something else?
720p TVs mainly look less sharp, but I can also notice significant screen door effect on 720p plasmas. It depends on the model a bit, but most at this size have it pretty bad. This is what I care about more than sharpness.
It is also worth considering what the tv will be used for. If it is for gaming, the plasma will have a much faster response time, but it will suffer from burn in. Whenever you play a video game for a long time on a plasma tv, you will end up with an image of logos, compasses, numbers, etc. Burned into the screen for a while afterwards. In my experience, they can last a few minutes to several days. It can also become permanent if the image is sustained for an extremely long time.
Samsung plasmas do have very good color reproduction. I haven't paid huge attantion to their LCD tvs but their LCD monitors are really awesome.
