I use a TSE24, plus an Acratech GP Ballhead with the Lever Clamp (Arca/Swiss compatible).http://acratech.net/product.php?productid=69&cat=1&page=1
(At "clamp type", select lever). So my rig cost $430 including the levelling ball head.
The clamp is marked in millimetres (etch a small vertical line on the camera plate for reference) and the body can be slid about 15 mm either way to compensate for parallax shift. I shift the lens "x" mm one way and the body "x" mm the other way - which keeps the lens from moving laterally. The loss from shifting the body 12 mm is negligible in the final image.
520 euros isn't pocket change (yet).
