Small Scale Military Headquarters

I've avoided these things for years, but I think I've now fallen into another collection. I bought my wife a 737 for mother's day (I'm such the charmer), and there are a few I have my eyes on, especially the C-5. Is there any good sites out there showing diorammas, etc people have set up. Also, are there any brands that are crap and should be avoided? Thanks.

I collect this scale. Don't know of any diarama sites offhand. Most current brands are pretty good, haven't ran in to much crap as of late. Aeromini is the cream of the crop as far as collecting goes but they fetch a healthy price. Gemini are my modern favorite.
