I've been in the same shoes as you. First looking at the Dark Impact but came across this SB V2. Sweet car indeed, but if you plan on upgrading look into the not even released (Feb 07 in the US) SB V2 Pro.
That baby is nice. It costs a little more, but you get a great package.
Dave G, please tell me that the Por will come with a clear body. I'm comfortable with my sexuality and all, but that does not mean I want a pink RC
