I look for the correct shapes and dimensions (it is not impossible to do,,,,,it can just be a lot of work to find all you need, sometimes)
I have a fairly large stash of both very old and very new kits,,,,,,so, if something is not going to be as accurate as some other kit,,,,,,,,I just don't buy it
if it is a new release and the only one ever done of that aircraft in my scale, I will buy it,,,,,,,,but, if it is the October 2013 release of the F-4B Phantom by Wooop-Deeeee-Doooooo models,,,,,,and they don't get some key dimension right,,,,,,,it is NO Sale
I am "seasoned" enough to just build and detail out an AMT F-4B again, instead, lol
but, release a Kaiser-Fleetwings XBTK-1,,,,,,and I will buy one, and either build it OOB or with mods to make it correct
