I need to make a decision...today if possible (as I am returning an SD Plasma) 42" Pioneer 434 for $7,000 (AU) or 50" Pioneer 504 for $9,000 (AU) The problem. The 42" is new in the box, the 50" is the shop demo model. Estimated demo time is 6 Months, at approx 12 hours per day, 7 days a week. I'm told that Pioneer Aust has no more 504's so, this is it if I want it. If I understand it, the 504's res is 1280x768, which is the exact res of 720p? Is that right?...if so, I'd assume it would be much better at displaying 720p that the 42" model which has 1024x768 res? So, any words of wisdom to assist me in making my choice?
