i've had 3 of their pods and highly recommend them. currently i'm using this one
HERE.
it's their AT-A104T. it's rock solid. i was using it with a 600mm this morning.
it's a giottos knock off and would be about $375 from them. mine was just under 100usd delivered. when set up the top plate is at 63'' with the column down. add a head and the camera and the VF is too tall for me to see thru. while you're at it pick up a
ATH-A01 ballhead. it's also a giottos knockoff that would cost you $200+. it's excellent and supports up to 8K or 17.5pounds.
i also got one of these for an offer of $100 delivered. i had to modify it a bit but its great for my super lenses.
