maekju,
I'm one of those paranoid people and have three CG Ultimate kits collected over the last ten years. One of them is the newer laser cut version. I got them in case I need repairs but I never totaly destroyed mine yet, it's being rebuild. And i have a framed spare sitting there just in case. I wonder if it's better to just completely destroy it that way you build a new one other wise you get attached to it and keep repairing it.
As a note I got a member in my club involved in building and he quite enjoys it. So I told him if he builds the ultimate he can have one of my spares. :-)
