Hi Grant,
I have one of Quartermasters backpacks, but you can also get one of Dirty Boys of the forums also. you just need to PM them. Also i followed Pandatroopers build thread for my T21 also available on the forums here as well. was originally hoping to get to your armor party, but cant make it unfortunately. if you are going to Philsy's next BnB i will have my pack there.
