I recently completed my first GB uniform, in black, with Neutrino Wand from Matty. I'm very eager to build my own pack too but lack some of the necessary wiring and crafting skills. It would be great to learn how to build one from any NE organization whose willing to help.
A few months ago I met a few of the GH of NH at a Pop Culture Convention in Wilmington, MA who seemed like pretty cool guys. I'm not sure if any organizations have open enrollment or active recruiting but I thought doesn't hurt to try.
