My LS443 is unrepairable according to the woman on the phone at Kodak (after only 2 years the lens is jammed). So, she said that I can send in my inop camera and for $125 they will replace it with a "refurbished" DX7630. This camera is a 6MP and reviews quite well.http://www.dcresource.com/reviews/kodak/dx7630-review/index.shtml (Yes I know it's just a Kodak and nothing special but I'm no professional photographer either.) Is this a good deal? It's definitely an upgrade from the LS443. Should I worry about buying a refurbished camera?
