I was looking at the Letus/Zacuto Studio Handheld Kit and I was thiking to myself that maybe I can build myself one that does not cost over $4,000. Basically I already have the IndiRails Pro system. All I need is the hand grip and shoulder pad. For those two alone, it cost $1,000 from Zacuto. So was hoping someone in here will have links to stores or sites that sells various parts to complete the hand grip and shoulder pad set. Any help is appreciated.
