Hi all, I was looking at getting the full auto 1400... I would like the 18lb thrust one more, anyone know how much longer? Anyway, do I need the ready to run accessories package for $169.00 or does the full auto version come with this stuff. I will upgrade the pump for another $100. I was also wanting the one piece tail cone but don't see it on the web, how much are these and where do you get them. Anything else I need? Thanks!
