Hello! We are looking for a good slider for DSLR use that is of good quality and has either a motor or a flywheel to make the movement really even. What slider would you recommend if in the less than $500 range?
It can be of about 80 cm (30").

Shark Slider S1 works well for me.

The S1 is a great slider but is going to be closer to $650. Slides are buttery smooth with the flywheel.

looking for a good slider and found this one:

Kamerar Fluid Motion Slider Review - Low cost High-Value - YouTube

kamerar fluid motion slider. about 250 euro. I have never used a slider but maybe buying a cheap one is not a good idea.

any thoughts?
