I've had bad experiences with PLT. I used it for my senior project and ended up having to rewrite in Common Lisp because I kept running into bugs in the interpreter. I'm guessing that Arc compiles down to a pretty well-tested subset of PLT, but if you start messing around with obscure libraries or really beat up hard on the macro system, you're asking for trouble.
