It's actually pretty amazing how much SHS has put out in the past 20 years. They may not have put out the mega-catalogs like Lionel and MTH, but for a small company, the two guys from Jersey did all right.
Even American Models, even though they only put out one catalog a couple of years ago, has put out quite a fair variety of equipment since 1985. Hopefully AM will get rolling again soon.
Add in the new scale proportioned stuff Lionel/Flyer's been doing since about '03, although all hirail 'till this year, River Raisin, S Scale America(formerly Pacific Rail Shops,) the dearly departed Omnicon and Southwind Models, plus Overland's brief foray into S many moons ago, there's been quite a bit available in a scale where "nuthin's available!" 
Now, if we can get Woodland Scenics and Walther's involved in making S scale structures...
