Jason, do us a favor and stop the all caps please. It makes you seem like you're yelling, SEE WHAT I MEAN? It also damages your credibility when giving advise, makes you seem more like a noob than you really are. :)

Anyway, I'd go with the 9920 because it's out right now. While the Mamba Maxx would be a great controller, it isn't out yet, and we don't even really have a good idea of when that'll be.
