I live in Jacksonville Florida and drive to Miami once a month. A store in Miami has the 6580n H.P. set I want for about a grand less with stand than H.P. has it on their site for the set alone. My fear is taking a trailer down there and buying this set only to get it home and finding somethig wrong with it. If I buy it there will I have to return it there or would H.P.'s warranty take care of it?
