I have a cheep $40.00 tripod that I have been using it works ok with just a camera on it but I built a slider and mounted it on and it moves way to much and is just not sturdy enough for the pressure the slider puts on the removable mounting plate what would be a good tripod to look for in the $200.00 range or would I need to spend allot more for something steady and robust enough to mount the slider on? slider worked great on a table test but it limits were I can use it now...
