Query: Only Lasted Four Months!

My wife and I loved the unit - nice styling and lots of functionality. After four months the power supply went bad and it cost $35 to ship a new one out of warranty only to find the LCD was now bad (black screen). We had NO trouble getting a hold of tech support at Polaroid for either issue.. but after the 90 days warranty expires they only have a $160 replacement to offer. VERY disappointed! Definitely purchase an extended 1 or 2 year warranty if you decide to buy this unit
