... while its still there. I bought the Steadyrig ex-demo Silverspring arm two years ago .... I'm glad I did - it's terrific. I have flown everything from a stripped down arri II-C to a BL-4 and with LOMO anamorphics and an Panny LWM and motors ... still haven't hit the bottom of the travel. This is a rock-solid, smooth as silk arm for any sled and camera configuration - grab it at half the price of a new one while its up!
