I have a GM-8 for sale. The mount has always been stored in a Doskocil Case which holds the mount, electronics and counterweight bar very snug and is in excellent shape. The case is included in addition to the upgradded metal motor covers, replaced teflon washers, a 7lb and 11lb counterweight and upgraded aluminum mount bolts. The tripod is in very good shape but have holes for the EQ Bolts which are not slotted. Otherwise it is no different from the others. I will include an army duffle bag which I keep it in.
My price is $1350 shipped CONUS.
Thanks for looking, Owen
