I'm looking for a good pan head video tripod that will let me remove the head, place a slider on the tripod, then put the head on the slider. If I get someone like this, should I also purchase a head separately so that I can tilt the slider and also tilt the camera on the slider for more degrees of movement, or would putting the slider on the particular tripod without the head do this for me already so that I can just purchase the tripod without an additional head? As of right now I'm looking at getting this: http://www.amazon.com/Dolica-AX620B...&qid=1345634930&sr=1-18&keywords=video+tripod and this: http://www.amazon.com/ePhoto-Profes...=1345606782&sr=1-1&keywords=video+tripod+head My slider would be placed in-between. What are your recommendations? Anything good for around $100?
