Hello,
I googled up some sliders of around 200, one from 100 and a cheap homemade thing:


Glidetrack ? Portable video camera dolly system for film makers (http://www.glidetrack.com/)

B. Hague & Co. Ltd Tracking Systems (http://www.cameragrip.co.uk/acatalog/hague_cam_slide.html)

indiSYSTEM - indiSLIDERmini (http://indisystem.com/products/indislider_mini)

WatchMojo TV - 5min - IndyMogul - How to Build a DIY Camera Slider (http://www.watchmojo.com/tv/5min/IndyMogul/321565138/)

I need a set up for filming ants, especially when they move on in groups (which they tend to do when foraging or robbing). So something on ground level.

Have you guys any experience with some of these linked items or maybe a suggestion for something better/cheaper.

Many thanks

For about $160.00 I built the IGUS slider shown here. Made from same materials as commercially sold sliders.

Thanks,
I am trying to get the materials here in Hungary.
