Another vote for The Titan Tower...
$1300 shipped: custom made for your boat, stainless tubing, collapses in no time at all, insanely sturdy (designed more intelligently than all of the other towers out there if you think about it from an engineering perspective!), looks way better than a monster.
Nothing but good things to say about the tower. I have no ownership bias, I've just dealt with lots of towers (just having been around wakeboarding for a while, having worked on boats and towers a lot). The Titan is the best way to go for that boat in my opinion!
