It's really hard to say without having used them. Just based off of my past experiences with similar machines, I'd go with 3, personally. The jump to the forth (the electric) is a decision you'll have to make. I wouldn't touch it if it doesn't come with a good warranty.
Hmmm, thanks for the input so far. The linear gripper I suppose is the little "thingie" at the bottom of the stick that holds the weight. If so ... then number 1 also has one...
What is it about number 1's mounting system and or clamping that makes you go "no no"?
Edit. Also ... what is the practical advantage of a linear gripper???
