Do you have any friends or relatives who have the Warthog? I suggest you try it before you buy it then make your decision from that.
I bought the Warthog because I'm a nerd and have some money to burn not because I need it to be honest. Its not perfect and for some people its not worth the money. For me, after add an extention and make DIY for the mounting it became my primary hotas. (I have CH Product and X-52).
