I'm looking for information about where to look for used crates. We're adopting a rescue soon (maybe this weekend), and want to keep the upfont costs down as much as possible. I've looked in the local paper's classifieds, but haven't found anything. Of course, if we can't find a used one, we'll buy new, but we'd like to try and avoid that. Also, is there anything we should look out for if we buy a used one? Thanks in advance.
