I have a GPS11 with all the standard equipment that has never successfully found itself however once you tell it what time it is
and where it is it realizes it's not a toaster oven and is remarkably accurate. A star gazer friend says it has superb optics. No scratches, dents, dings, rust or dust. Also included is a jmi hard shell shipping/carrying case. $2000 plus any shipping/insurance from Colorado Springs area 80106. This thing is just too big for me to handle alone.
