Expensive but unique and useful for specific work.
These are way too expensive unless you win a lucky deal, but if you can afford one and you need it, you will know how good they are for their intended purpose.
Don't buy this unless you are using a lot of 3d CAD and design software, or game creation toolkits, and pressing SHIFT CTRL - DRAG etc. to move the viewpoint gets on your nerves. If this is what you need, it will set you free, if you don't need it or try to use it in the wrong scenario, you will wonder why anybody would want one!
