I've been hunting around for a trailer recently myself, but have been hesitant to spend the money required to get a good one. The other day Hans Trailers were advertising on TV, and they look pretty good to my uneducated eye:

and reasonably cost effective:

I particularly like the hot-dipped gal finish, would be good for up here, with the humidity and the amount of rain we get. As a long term investment, it probably makes sense for me. This one particularly looks good to me as a general purpose "take stuff to the dump" trailer, but again, I don't really know what I'm looking at:

But looking through another thread on here 10 mins ago, I came across these:

Now, obviously, they're a cheap trailer, and won't last as long as a "good" one. BUT, they ARE cheap, they seem to have a good rep, and they fold up nice and small and out of the way.
Just a couple of thoughts from someone who doesn't have either...
Thanks!
