hi im using a benro b-0 (their new series ballhead). seems to be of good build, and very nice to use - have friction control (with 1to12 graded markings), and placement of main tightening screw very convenient (and screw very big, nice to turn). got panning also, with angles marked out.
the b-o can take up to 8kg, retails for less than sgd200 at benphoto. quite a gd deal actually. plate mount is the arca-swiss mount so can buy alot of other plates that are compatible if you want.
quite satisfied with my ballhead so far.
do not be coerced into buying the older series like 'kb' or 'ks', the build is horrendous.
but the "b" series listed in their new catalogue. catalogue available at shop.
