Redrock Micro is releasing a new line of configurations on it's website called 'nano DSLR Rigs', targeted for lightweight support DSLR rigs. Still a bit too expensive for something as simple as a handle or two, but these parts are designed to be compatible with more Redrock gear as you grow. Information from their website is posted below, you can find their storefront for the Redrock Micro nano DSLR rigs here.
nano DSLR rigs are compact, economical rigs designed for maximum value and discreet shooting. These rigs are a great value for photojournalism, travel, and documentary style HDSLR shooting, or as a great entry level rig, easily upgradeable to additional features found in our DSLR handheld, shouldermount, and studio configurations.
