None of which really matters on a tripod. Just saying...
My FH1 has pretty horrid stabilization. Depending on usage. But even on a tripod, if you've got your hand on the tilt arm, the shakes and stuff can translate across that and affect your image quality. Even the boom boom of the club can translate through the floor to the camcorder. Granted that my tripod is probably lighter than the camcorder. Which is pretty light. On a monopod with a spider brace to it, I can move about and not get too hideous in the process. The shakes can be anything, age, nerves, nervous wreck after driving through stressful conditions for hourS to get to the shoot location, fatigue, .... It doesn't take much to challenge even the best of internally stabilized camcorders.
IMO a good stabilization rig, even DIY wise can be a better bang for your buck than that $500 extra in internal camcorder stabilization. But mainly because you can't take that with you to your next camcorder. As I look at possibly making one of these type of rigs.http://www.youtube.com/watch?v=qZtlSVgG1h8
1:40 into it is the version of interest. Functionally about the same as I currently have / use. Without the bulk of what I currently have. And some option to accessorize / pimp out, your camcorder. At a minimum, having a straight rail to use as a sort of gun sight to see what you're pointed at while fully zoomed in is a sanity saver. Versus having to fully zoom out, figure out which blade of grass is host to your lady bug friend and zooming in without loosing her. While still having the mobility to follow her when she flies away. For those of us without view finders or who increasingly find our camcorders further and further from us, but still need to see the LCD.
