For that price range, I'd buy an STL for trucks, and other logistic/supporting vehicles/tools/equipments/crew that can be put in a hangar/airfield set/diorama next to my 1/72 model kits.
Actual resin is too much for me because of shipping, tax, customs. So i do prefer STL.
Atm my option for those kind of supporting vehicles/tools/equipments/crew are hasegawas conventional regular real life model kits.
