Panofix camera mount?
The PanoFix is a basic pano head that does everything that I want it to do, but I don't shoot gigapixel 360 degree vitual reality shots. The strap helps me when I'm in the field carrying my camera on a tripod or monopod to prevent the camera from unwinding off of the mount. If you don't carry the camera mounted you can easily remove the strap.
As for the need to move up later: I know people who own the fancy erector set type and leave them at home because they are too much trouble to carry and set up. My PanoFix only weighs 5 OZ and fits in my camera bag fully assembled.
