I've used the 4m and 2.4m Impact light stands that B&H sells and they work just fine for me. Monday night I had a 1m boom attached to the top of the 4m stand, with $5k of mics hanging on the end with no worries. I did bungee cord the base to the end of the pew, and camped out next to the stand to deflect wookiees. (In most of the concerts I record the wookiees are little old ladies with a touch of dementia. However, they can be just as destructive as Big Dumb Dude with Beer wookiees.)
