Has anybody used the AX2000 or NX5 with any of the available shoulder pad extensions? If so, can you recommend one that is not too expensive? Doing a search on B&H comes up with like 23 pages and tons of different models, so I would like to know of someone that is using any of them and that feels comfortable after holding the camera for hours. Basically I would love to have something that can make my AX2000 as comfortable to use as my older HVR-HD1000U, although obviously it's going to be heavier, but the AX2000 is really uncomfortable to hold steady for a long time.

Thanks,

Sebastian
