FYI you don't need to setup a trust. So you can save a bit on that if you choose not to. The paperwork is not particularly difficult. The part that sucks is like you said...the cost and the long wait time. Yea ATF's rules on suppressors are pretty freakin stupid. A guy next to me today was shooting the same exact rifle as me (RPR in 6.5 creedmoor) but he had a suppressor on his and it was SO MUCH more quiet! I took my ear muffs off when he took a couple of shots and it was perfectly fine.
