TOTALS
To purchase NEW this system is worth aprox - $9405.95
I am selling it USED for -$5,230.00 (OBO within reason)
That is a savings of aprox $4,175.95
This system should be in perfect working order. I have stored all of the equipment in a sealed car garage so it has not been exposed to the outdoors (excepting the plastic garden beds which were washed outside).
Please only write if you are serious about purchasing this equipment.
