I often find myself on Ebay, looking at and purchasing some very rare and expensive kits. Many of which I only see available once, or once in a blue moon. I personally am the type to build everything I purchase, no matter how rare or collectible it is. I know for sure that in doing this, or even breaking the factory seal in many cases, that I am killing virtually ALL of the value in these collector kits. I'd just like to know;; What do you all do with kits like that when/if you make a big dollar purchase or score a rare collectible kit..? Do you store them on a shelf and not touch them, or do you just build them the same way I do..? On occasion, I get nervous about breaking the seal on certain kits, but it seems that in the eventually I just open them and get into the build anyways.I'd like to know what you all have to say about this..---- Nick R.
