Hi everybody, I'm new here, and here is my doubt:
I have to do a video upon contemporary artist's "paintings" (nails, woods, burned metals...)
I thought something like vertical dolly very closed to the "canvas" (capturing the materic nature of the paintings) maybe with very shallow DoF and macro lens, and may in timelapse rather than in video.
Then I thought I need a motorized slider, but it should match 3 details:
1. Working in vertical mode (on a single tripod);
2. A minimum vertical-payload of 3Kg (5D3 + lens + spheric head);
3. Possibly cheep...

I found only 2 models that match the 3 details (and that can arrive easily here in Italy):
1. Proaim Spark + VersaSlider 2;
2. RAM Motorized Slider Bundle by Revolve.

Both are in the same price range: 300/400 euro.
Proaim Spark is the poor coppy of the innovative Edelkrone slider, and VersaSlider2 motor is expressly designed for Proaim.
RAM instead is an all-in-one but traditional solution.
From specs, both can handle the vertical payload of 5D3 + lens.

I'm inexperienced (but I have to make a fast choice) so, please, can you kindly give me an advice?

Thanks a lot!
