If you are a model-maker, you can search for AMT
model kits, like this one:
their index of Star Wars Model Kits is weak, but they have a couple here:
I built many of their models for Star Wars and they're brilliant. Great detail and lots of pieces. The Millenium Falcon had over 150 pieces---painting and assembly took me over a month. It's 18 inches long. It's the best model-kit I ever owned.
The X-Wing, Vader's TIE, Sandard TIE, and Y-Wing were made to scale with each other. (about 7-10 inches long)
The scales of the other AMT models differed, but if I remember, they also made:
The Tideriun shuttle,
The speeder bike (with pilot),
The Star Destroyer,
...and probably more.
They had a Snap-Tite series that included:
all of these were about 4-6 inches long (to scale with their Millenium Falcon Model Kit).
