I've been using the SmallHD DP7 and loving it, but it's pretty heavy. Using it on top of my GH4 with a hot shoe swivel head is clunky. It falls down all of the time. Comes loose. You name it. I searched the market for anything that would attach both sides of the monitor allowing for swivel, and a sturdy grip. Found nothing. I decided to build it myself out of parts found on eBay, and B&H.
Here are the links to parts I used:
SIDE RAIL CLAMP: http://www.ebay.com/itm/281056066980?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
2 PACK OF LONG 1/4"-20 SCREWS: http://www.bhphotovideo.com/bnh/controller/home?O=&sku=920351&gclid=CPqemNGJ1cACFYk7Mgod2EoAfw&is=REG&Q=&A=details
2 LONG BRACKETS: http://www.bhphotovideo.com/c/product/1062515-REG/desmond_d3d_3_mini_stereo_camera_bracket.html
I'll admit that this isn't ideal if you need to mount a microphone, but if you're going handheld for video only it's sturdy as hell.
