the ones your looking at are made by atlas which are excellent ( i have some but always looking for more )
there are some cool new ones made by latchlake music and brought in by legacy audio in QLD i think
AEA do one as does manley
but what you are really seeking are the film scoring set jobbies made by mole richardson
there are the ones you see on the scoring stages etc
new your looking at $2000- 5000 but they turn up from time to time 2nd hand in lighting equipment sales pretty cheap
matter of fact they are really modified lighting stands and with that little bit of information you may do better in your googling
so they DO turn up cheap
if you can beat me to them
