i was going to say for 300 you can get a ua5 and have a bm2 mod done
i would do that before i got this, but then again this is much smaller and stealthy if thats what you will be doing with it
you would prob need to check into powering it
it says 4hrs typical with no phantom
so you can bet its prob less and then if you have phantom turned on you will get even less
so depending on the shows you tape it might not last long enough
