I don't care what's in or not. The only thing about newer versions coming out that bothers me is that I am trying to stock up on things. I love my Protank 2s and do not want 3s! I have been accumulating coil heads so that I can keep on rebuilding them for years to come. I want to be able to buy more PT2s, PT2 minis and EVODS (and parts). I worry I won't get enough of them before they get phased out completely. Money is tight in my household, so I can't just order a bunch at once and be done.
