Buy the Rhodes. You won't regret it. You can pour money into a clapped out Mac that you will never get back (and apparently you need to dump money into the trailer as well- come on, ask yourself, if the guy cut sloppy corners on the trailer, how well did he do anything else on the boat?), or buy a boat that is a) still in production, b) was much better quality to begin with and c) has a fanatical following, parts support and d) you can sail now without work.
Nobody has ever gone wrong buying the best boat they could afford, but a lot of people have given up on "bargains."
