Experience with Sushi Maker?

Honestly if I would have to pick a dish I have to live on the rest of my life – it would be Sushi.
I die for good Sushi! Yummy!
While surfing the net for reviews and new sushi restaurants I came across this side:
Sushi Magic
Hm they have these Sushi makers in their shop and I wonder if that thing works or not. I have made Sushi on my own with a bamboo matt and all those nice ingredients you need.
Frankly I thought it would be more difficult to do. Ok, the inside outside rolls, the ones where the rice is on the outside, is harder but after I while I figured it out. That´s why I am not sure if a sushi maker is a good investment or not.
Has anybody experience with a Sushi Maker? Please let me know which products you tested and if you liked them or not.
Thank you in advance to help me in my decision
