yep, you really do need to adjust the collimator. The last GSO collimator I got looked like it had been assembled by hammer. The adjusting screws on the side of it were loose and the laser assembly was flopping around. Totally useless, but it worked fine when it was adjusted up. Alexander posted a nice summary of how to do it..
