Windows up on arm

I'm try to find something compatible with the alarm that I have.  It's an Alpine 8026A. What I want to happen is that when I arm the alarm I want all three of my windows to go up.  Yes you heard me right.  I have a '93 delsol and it has three power windows.  There's the two on the side and the back window.  Now for the most part I've only found window modules that have either 2 or 4 window capabilities.  Also upon reading some features of the Crime Guard Au93-4 it says that I could just hook it up to my alarms starter disable output.  It's also has momentary, constant, positive and negative trigger compatibility.  Does $49.99 sound like a good price for this thing.  It's a 4 window roll-up module but could I just use it for 3?

yeah forget the price.  I've already found it cheap somewhere else.  I guess my main question is, would this thing do what I want it to do?
