Hello Continental boy!
Feel free to check out the threads titled with Aero Displays on the heading in this forum. I build 3 dimensional airport layout bases. You can put your own buildings on it or the Herpa ones. If purchasing an airport is not your style feel free to check out the attatchment pics for some ideas. If I can be of assistance to you or have any questions feel free to ask!
