I only have experience with the overpriced trendy brands, BOB and BAW. My dispatcher recently bought a BOB knockoff, which was heavier but cost much less than a BOB. Sorry, I forgot the name already, but I can easily track it down if you like.

As long as you are considering trailers with 100lb capacity, you might consider a single wheel trailer. They track behind the rear wheel much better, no big truck wide cornering concerns. Single wheel trailer leans into the corners as opposed to double wheel, which want to flip to the outside and I have put my BAW on it's side several times, the BOB never.
