Vixen half pier (which has a few marks and scuffs) for sale -the one show here:

It also comes with a modified head to use with the AZ-EQ6 but may still be used for a vixen GP mount. $150.
Note neither the tripod nor the mount shown in the photos are available. I will upload more detailed photos of the pier later.
