I have a professionally made powder coated pier surplus to requirements, so second hand but unused. Original cost around $800 earlier this year, will accept $600.
Photos attached one showing pier with my G11 and adapter pipe (not included). You will need to provide an adapter to suite your mount, the design makes it pretty easy to attach.
As it was designed for a G11 and I would point out a potential problem with smaller mounts and that is the top plates are 320mm diameter which may get in the way without some 'adjustment'.
If you are interested I can provide more detailed description and also happy to meet somewhere convenient to deliver say Yetholme Caltex.
