This blog runs through a few video and photography heads that are useful with the Digislider or similar camera sliders.
You may find that a lot of tripod heads mount fine on flat surfaces, like the carriage of the Digislider, but the panning resistance adjuster, near the base, is often restricted by the carriage, like the following:
Manfrotto 701HDV Fluid Video Head - £79.00 - amazon.co.uk
If so, you will need a riser or a like the following:
Manfrotto 120 converter 1/4" Male 3/8" - £15.00 - amazon.co.uk
E-Image EI-717AH - £60.00 - proav.co.uk - no need for a riser
