Hi Fran,
Know where you are coming from.  At 78 it isn’t easy to transport 15000 from second floor.  When no one is available I have to go down stairs kneeling and facing machine as I lower it one step at a time.  At my age I can’t risk tumbling down stairs with 15000 in hand.  I have a friend who uses her chair lift to carry her machine up and down.  Anyone out there have other suggestions.
