I don't own that particular machine but I have a normal looking functional trainer where it's a cage and 2 stacks on each side.
I think It really depends on what your goal is? For weight lifting? For ^ weird explosive training^. I use mine for strength training. But if you know anything about strength training, cable machines generally don't offer the same resistance/tension free weights and to a lesser degree leverage machines do. So most people will use them for finisher sets.
With any machine system you have to look at the weight limitations. Ask your self: Will you ever outgrow the weight stack? It's a legitimate concern.
Another thing about cable machines you should know about is weight ratios. Cable machines use pulleys. Pulleys can give you a mechanical weight advantage which reduces the actual weight size of your stack. IE 100 lb stack is really 50 lbs. Now you are probably wondering why would they do this? It's essentially done to increase the range of motion. If your cable pulley was 1:1 the length and overall range of motion of your cable would be short because it would be hitting the top of your weight guide. Functional trainers range from 2:1 to 4:1. So a machine with a 200lb stack with a 4:1 cable ratio would only be 50 lbs of resistance. That isn't much if you thought you had a 200 pound stack and you were going to use it for overhead presses or rows. The machine you linked has a 3:1 ratio and like a 120 pound stack.
I wouldn't buy one but I assumed OP meant to use at a PT center or gym. Resistance bands also vary throughout the range of motion by design where the keiser is air compressed and (mostly) static. Unless that lotto thing comes through tho not popping for one and the compressor and other crap required anytime soon. I like em, but not that much! That's 50-100 pairs of gloves kinda money!
Couldn't you get some looped bands of various resistance levels, set up anchor points (high, medium, low) and basically replicate the same thing for a fraction of the price?
