Based off of parts from standard grip equipment, the Carry Cart is a $1,600 modular camera cart that you can build as you see fit. The Wedge is a $250 plate with three small legs and levelers so you can put a camera where you can't take a high-hat. The Cam Tank is a super robust $1,450 low profile plate with old school pan and tilt functionality to add more tilt to your existing head or for low angle and cramped shooting situations.
