I haven’t used the Edelkrone Sliders but have only heard awesome things about them. Does that particular slider have the tracking mechanism that allows the rails of the slider to move with the camera (so you ended up getting more slide distance than actual length of the slider - I know thats the big draw with that brand)? I considered Edelkrone but ended up going for a Rhino 2 foot Stainless PRO.

This one looks like a nice, budget-friendly option as well: https://www.amazon.com/Neewer-17-5lbs-Capacity-Stabilizing-Photograph/dp/B01FJ9HEGO?th=1&psc=1

Same brand from the link you sent but these come with carbon fiber rails so it’ll be more lightweight than most sliders. In retrospect, I would have went with carbon fiber over stainless steel. The less weight you have to carry around, the better. Good luck on your gear search and getting prepared for the wedding. Let us know if you have any more questions!
