I just got my first Beaver Box Mod and it will not be my last. The picture below is my new 26650 Mechanical Box Mod with my new Troll v2 RDA and a matching drip tip I had lying around. I can't say enough good things about this mod. It has a perfect hand feel and a great click firing button. I asked David (David Poston, the man behind the mod) for something with purple and green and he came through with an amazing combination. The mod's finish shines and it is just a pleasure to use. Check him out, you won't be sorry and his prices are really quite reasonable. $200, give or take for a handmade, custom designed mech mod.
