I use a number of CPM camera rigs and they’ve done a pretty good job, but the price can be a little out of range for many budgets. A CPM cube cage for example will run you around $260, not a bad price, but still more then some of the lenses people film with.  However, if you keep an eye out there are always deals to be had. Up for auction is a Frankenstein CPM rig with handles, shoulder pad and counter weight. Current auction price is $102.50 + $30 shipping with 1 day left. If the price stays under $200 it could be a pretty good find, though it does look like it might need a few more parts (i.e. quick release plate) to get things finished.
