Personally I don't see why you need to upgrade chargers. The Mill. Pro is still a fine charger so unless you have a real burning desire for something new don't spend the $$. Buy a good discharger instead (integy or spintec).
Good point. I will leave the charger to my last decision and if money's tight, I'll pass. The charger has been good to me. I think maybe I'll spring for a better power supply as I have never been 100% for using a computer power supply. I've had the charger false peek on me a few times, I've accidently hit a pack once when it was charging and then it just stopped and false peaked.
For the chassis if the cost of the Corrally does not scare you then get the carpet version of that and you are ready to race.
So the carpet version should be good to go right out of the box, without having to spend the extra $100 for uprades? That's good.
