Ninja has all the above, plus heat and a extra 100psi.
But in my book its all to expensive, i looked into all this vanmount buisness.
And the ninja with all the extras come to around 4k, then you gotta get water tanks and a pump etc.
A Woodbridge starter t/m is around the 6k mark, and i would think it would out-perform them all, will last longer, will require less messing about and will look more impressive.
If you do mostly domestic, and can get a setup like this between 2-3k its prob worth it, but at 4k :
id rather have the real thing.
