It all comes down to the "why" i want a prop.
Usually it has to be Star Wars, to be even noticed by me.
But - i have some ST stuff for deco reasons, to use it in my ST-themed Home-Cinema. Cause SW props wouldn´t mix good with the ST ambience. I have no other ST-props than these that can be used in the ENT-"world".
Then, on very rare occasions, something others catches my eye - but it has to be something special for me, to contain the essence of a movie i loved once - as the Conan Snake Amulett.
But as a prop, just cause it is a prop - it has to be SW. It has to be equipment, be it a blaster, a com, a welder - no set decoration, no custume stuff.
And it needs to have the special SW-feeling for me, not everything they used makes me feel "SW".
Then it has to be made in a quality way, i prefer good craftmanship over accuracy. I would never spend even 50$ for a wonky but accurate Stormtrooper or Vader helmet - it has to be made perfect symmetrical, straight lines, defined curves, .... as it would be "in real", not like butchered together by some guys in a hurry, to be used in 1 or 2 scenes.
