After finally deciding that Pioneer was the brand I wanted to purchase I waffled between getting the 5045 and 5050.
The 5050 is using the same plasma panel as the 1120 which has some pros and cons - the pros being a slight improvement in PQ with the "first surface pure color filter" and the cons being more plasma noise. I have visited a couple of different B&M establishments that carry the 1120 and I have not heard "buzzing" or plasma noise that I would consider excessive or unacceptable. I'd be lying if I said that I am not concerned with folks that have reported "buzzing" problems with their 1120 units, but I would have to think if this is really a major design flaw that Pioneer would not have proliferated use of the same plasma panel to their next generation of 50" consumer units.
I am sure that some of the changes made to the 5050 have been made to reduce manufacturing costs - but that can be said for most consumer electronic products - afterall faster, better , cheaper is what drives new technology offerings. Having said I have decided that the slight technology improvements in PQ of the 5050 vs. the 5045 outweigh any cost reduction efforts that could be perceived as lower build quality.
I have placed an order for a 5050 unit this week and will be anxiously waiting for its arrival
