I use the sign video adapter and LOVE it! It works like a charm and the best thing is it's so easy because I can connect my tripod quick release plate to it. Easy on....Easy off. Plus, they have great customer service!
I have a "Rovercam" that is an xlr adapter that attaches to the camera and then the entire unit attaches to a tripod. I no longer use mine as my equipment is now xlr-native. It is in like-new condition and would be willing to part with it reasonably. E-mail me privately if interested. My address is in my profile.
