Hey if anyone is looking for a low cost alternative for 19mm handle bars for a handheld rig, I found a pretty good one. I just wrapped a feature film on my BTR1 and was looking for those handle bars only, but came across this one from Camtree... http://www.thecinecity.com/eshop/search.php?mode=search&page=1Good thing I found out because these ones are waaaayyy better than the simple handle bar that just slides on.

Our B Cam had the original Red handle bar grips only and those ones don't lock well, and slide around. These ones from camtree were rock solid the whole shoot, good build quality, light, and dependable. And the price was quite a bit lower than anything else I could find. Also they work for 15mm as well as 19mm rods. Check em out, definitely makes shooting handheld way easier... and as a bonus sometimes I was able to use it to shoot low level, on the ground type shots and could use the rosettes to adjust my level, like a mini tripod almost. Well worth the cost.
