I am about to purchase a Sony DSC-F717. Because Sony has such a poor warranty (only 90 days labor), I am planning to purchase an extended warranty. OneCall offers extended warranties by NSI, and Computers4Sure offers extended warranties by Service Net. Has anyone here used either of these service plans? If so, what was your experience like? Did you have to wait long for service? Were there any difficulties getting them to honor it? Thanks for the information, S.
