JP toys/ models

I've had the idea of making shadow boxes or small terrariums depicting scenes from my favorite movies and i really want to do a few related to jurassic park. alan grant and standard dino figures aren't hard to find on ebay. but does anyone know of any other shops/online retailers that might have either toys/models of the Main Gate and/or of the jeeps? looked on ebay, but the sets which include those pieces are pretty pricey.

I understand that what I'm looking for isn't in production, but if anyone knows of a place/website that just happens to have a ton of this stuff it'd be great if someone could mention it.

I'm assuming with the new movie new merchandise will probably come out, but obviously that's a little ways off.

JUST CURIOUS!
