Anthony, I personally have never heard of the bomb site tool and after searching for it on Google I came up with a blank, Other than changing machines I'm not sure what would be faster for you, I do know that Signwarehouse.com has what they call an ARM (automatic registration mark system)
I would suggest calling them and ask if this ARM system would work on your cutter. Or to do this cheaply get a laser pointer and fix it to line up with your cutter head, you will still be going back and forth to your cutter but should help you to speed up your alignment.
