I also purchased the PN50B550 and Home Theater System at HH Greg. I didn't pick up the TV yet and didn't purchase the Extended Service Plan either. I have a 50 inch Samsung DLP I purchased about 4 years ago and have had no issues with it. I felt that Samsung TV are very reliable and a great product and didn't feel like coughing up another $150 in profit to HH Greg.
I am picking up a Samsung PN50B550 (50 inch 1080 Plasma) today from HH Greg. I am comfortable with the purchase but should I buy the 3-Yr Extended Service Plan for 150.00? The TV cost was a bundle w/Blue Ray Surround System but lets say the TV cost was $900.00. I used my AMEX to double the 1 Year manufactuer warranty to 2 years but still cant decide if I need the extended service. Opinions? Expeience with my TV or HHGreg or other service plans. Need your two cents. I know this is a recurring question but I could not find current 2009 feedback.
