I haven't attempted habenero, i'm thinking that will result in something closer to V8's spicy variety (which I like also). My closest imitation is tomato juice (not V8) + chili sauce + onion powder. The only problem is the consistency due to seeds in the sauce (I haven't found a seedless version on the store shelf), but I'll take that over the hassle of sieving the sauce, and it comes pretty close.
