I discovered a place called "Little Guy Trailers" in San Diego today. Scott and Eric were very knowledgeable and there's no hard sell. They carry a variety of different lightweight towables, such as T@B teardrops, Aliners, Cricket trailers, etc.
What caught my eye though, was a 900 lb. metal/fiberglass trailer patterned after the German-made Eriba Puck. The "Meerkat" is made in San Diego and is really sweet! Check out the websites below. They can be shipped or picked up, of course.

At only 900 pounds, almost any 4 cylinder could tow it.
