H, you know your chucky's thats for sure, i never noticed the dungarees and hair inaccuracies on the TngTeam one, good spot.
Actually looking at the photos you found, it doesn't look as good as the one you did in all honesty, it's amazing what professional phtography does, this doesn't even look like the same TngTeam doll!!
I think i'm going to go down the route you took, buy a Spencer and modify, would i be right in thinking / saying that a buy it now, including shipping from the states for £60 is a decent enough deal?
