If 3d printing had better results (instead of the grainy finish) there is some great model variants like this:

Lambda also had a mold revision: first ones had issues with opening wings (they could not be opened completly), while the newer ones don't have this issue.

Falcon also had a revision in HoR. Its the same model after all (dish is separate part) but way more detailed (damage in particular: old one just have hole in one place while new have torn hull and some reinforced structure underneath there).
