I stash for a simple reason
there are about 5 moldings that I "don't have enough of for my collection",,,,,,,and they are all OOP and no longer available at even the second hand kit websites,,,,,I need about 25 of those moldings in total,,,,,,I will and can build around them and work them in later on in the build order, picking them up here and there at various shows when I see one or two of them
about half of my collection is now made up of kits that we either can no longer get easily or kits with markings options that have been OOP since 5 or more releases back if it is a specialty kit
so, knowing that over 250 are already OOP, it is not a far stretch to think that a large percentage of the other 250 will wind up OOP someday,,,,,,,and I don't plan to spend the next ten years searching for a specific molding every time I want to build a specific Aircraft and Squadron for my collection's theme
the "New" Academy Crusader is one example,,,,you can still see the original released F-8E now and then, but, the current release of F-8E has a different decal sheet,,,,,,5 or 6 releases from now, and you won't be able to get the first release's markings options
this is not a big deal if you want to build one F-8E to go with your one F-8J,,,,,,but, it can cause problems if you are trying to build a VF-211 F-8, a VF-24, then a VF-51 and VF-53, etc, etc, 20 to 40 times per aircraft type
