I did some searching through the forums and couldnt find anything exactly like this so forgive me if its somewhere on the forum. I was googling the other day and found a mount someone made (back in 05') using double sided 3M tape which i have seen before on this forum but this looks much better! The really good things about this is you don't destroy your suction cup mount and its pleasing to the eye. Anyway here is the link.

I already made one yesterday, the only difference's was that I painted the aluminum bracket black, screws were machine screws (not self tapping),1 nylon and 1 metal washer per hole. (parts minus the bracket were from a previous xbox360 mod) I am very happy with the install. I will post some pics of the finished install soon but its not much different from the link.
