Hi, I am deciding between 2 Fujitsu Plasma (please don't recommend another brand, coz' I don't need any more distraction): 1. The 50" P50XHA40US 2. The 55" P55XHA40US Fujitsu is offering $500 rebate for the 50", and $1500 for the 55". The net cost difference between the 2 will be $1,300 (not too significant considering the high price tags of either one) However, there are 1 important difference between the 2 that bothers me: It is the contrast ratio: the 50" ratio is 3000:1, whereas the 55" is only 900:1. Can anyone pleeeeeeeeease tell me if the 55" will be noticeably inferior to the 50"? From the showroom, they were playing DVDs, and I don't see much quality difference. However, I will be watching mostly Cable TV, would the 55" be a bad choice? Any comment is highly appreciated!!!!!!!!!
