Here's the story with this slider. It has served me very well for the last few years, but I need to sell to invest in some other gear. It was manufactured by a Canadian company, I'm not sure the name. Slider is well used but still in great working condition with many more years left on it. It's steel and Aluminum and very sturdy. Can easily take most heavyweight studio cameras. It has a Mitchell base on the top and bottom and works on a pillow block ball bearing and rail system.
Here's the cons. There is no brake on this slider. There are stoppers at each end but no brake on the base. I've never had a huge need for a brake, but I'm sure it can be a simple modification to have one installed by a metal shop. Cosmetically, it's got a lot of scuffs and wear but functionally it's in great shape. One cool feature is it can be easily disassembled and modified. There are a few different tie downs and bases which I'm including.
Feel free to call if you have any questions or need more pics. Slider is located in L.A. but I can ship anywhere in U.S.
