I own one Vaporized Nomads Boss 3000 and a second on the way. The reason I chose the Boss is because the 510 it flush instead of raised like on the Mad Modder. Both kick ass boxes with total customization, great cs, and max amp lipos. It's all on what you prefer.
Vaporized Nomads are great, stand up people. I talk to the owner Adam directly when ordering. Each company has some unique things only they do. They both do custom photo realism etching. But mad modder has the 1850 mini which is a square mod like the hammer of god and vaporized Nomads has the milled sides. Which ever you chose you won't be disappointed.
As you can probably tell I'm biased towards the Boss 3000. I have a zombie Boss number 5 of 6, it's my avatar for this forum. And on the way is a Batman and Bane Boss with milled sides. Looking forward to seeing pics when you receive either one. They are pricey but well worth it.
