I have found an Instep trailer for $60 on Craiglist here, but it looks like it has plastic spokes which probably wouldnt last that long.
Some of the plastic-spoked wheels I've seen were incredibly strong. Whether the hubs were of equal quality, I don't know.
So I refurbed that Bell trailer I was posting about a couple of weeks ago.
What do you prefer about the current version of the trailer relative to the original?
