Yet another request for DAQ hardware recommendations

Hi,

I develop a high speed image acquisition software and I would interface 
a daq to drive the laser source. The idea is to trigger a arbitrary 
function from the camera signal to modify the laser power ( voltage of a 
acousto-optic crystal).

The typical scheme would be :

a TTL signal is emitted (frequency fe is between 10Hz and 1kHz) by the 
camera connected to comedi_dio#0

the analog output is triggered by the digital input and start the 
arbitrary function ( a top hat function, 0V from t=0 to 0.8/fe, then 5V 
from 0.8/fe to 1.2/fe, then 0V from 1.2/fe to the next trigger from 
digital input )( note I need to be non-reactive to the trigger which 
appened at 1/fe ).
I used to do this with a external function generator and I would like to 
use a daq board.

Does anyone know a well supported by comedi board which have the needed 
function ( analog output triggered by digital input, +5V ), as I need 
several boards I also looking for a "not too expensive board" I needn't 
MHz stuff.

Thanks
