I wouldn't discount the Quik-Pak so quickly. Mine is 4 years old and absolutely no issues.
It's light, for a trailer.
It's waterproof and pretty robust.
It's very stable, over 40 mph down a hill with 2 weeks of groceries behind my tadpole trike and no issues at all.
The wheels are very decent compared to most trailers (same as came on the front of one of my bents) and it probably rides better than any of the 16" wheeled trailers.

Probably not a plus for you, but it comes with an attachment to convert between being towed behind a 20" wheel bike and a 26/700 bike. Plus the wheel and tire sizes are identical between my trike and the trailer.

The 406 wheels are also much easier to get tires for than 16" wheels, should you ever have a problem.

Mine was shipped over 8000 miles to where I use it more of the year, no intention of ever selling it.
