Oduman N2 - pull the trigger or no?

I am interested in the design of the hookah. I almost purchased one a few moments ago and thought I should adult the situation and get some opinions. If anyone whom has experience with Oduman hookahs my main concerns are:

1. Owning a Lavoo MP5, I want a hookah that's not tipped over with a strong exhale of thunder cloudz.
2. How good is the draw on the hose? Can you use different hoses with it?
3. Is there a difference between the n2, n3 and n4 other than slight design differences?

I am looking to buy a new hookah. I'd prefer a mostly glass as I love the look of them. So any suggestions as to an alternative is also welcomed. :o happy smoking guys.
