It's me he's talking about running bodies for under 1k , and I run Omex600. The charger idea would be me using the one from a mini.
Russ' £600 included re-couping money from bits sold, mine doesn't.
Your right mate, if it was done and the standard bits were kept then id imagine the cost would be around what yours cost.
Though the good point about mine is if you wanted to return to standard its piss easy, as you well know once you have the noise of bodies there is no way your going back to standard
What brakes/suspension are you runnng fella? You havent stated the current spec of your car?
