Help!! I need a good flight controller for a tricopter..

Hello all,
after I was ripped off by airfoil aerial systems with a very low quality t copter I am trying to buy better components for the t copter...
I allready changed the servos and I am planing on changing the speed controllers.. but one of the first things I want to change is the flight controller...
right now has the hobbykings KK2.0 flight controller... it works, but I don´t think it is the best choice for aerial photography..
I am looking at a flight controller with GPS so I can have position hold.. I have been looking at the DJI naza, but they don´t support a tricopter with tail servo...
I am also looking at the X aircraft autopilot but I can´t find if this devise supports tri copter with tail servo... do any of you know if this devise supports my t copter?
I did find the multiwii pro flight controller with gps but I can´t find any info of how good or bad this board holds the position..
so any suggestions will be very helpfull!!
thanks!!

I've got one of these... http://www.diymulticopter.com/product.php?id_product=70 and one of these on the way... http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=25437 the rest of the needed parts are already on hand in the spares and used bins. I'll let you know how well it works as soon as I have it all in hand and assembled, from the videos I've seen the altitude hold and position hold appear to work quite well using the Multiwii 2.1 or MegapirateNG firmware, have to wait and see if that's actually the case.

If it does do the job as well as in the Youtube videos it will be a real deal at roughly $140 US for the board with GPS, less than the cost of just the Naza GPS unit, if not then it should at the very least make a decent flight controller for one of my FPV quads.
