I'm a huge fan of Clojure, SBCL, and Clozure CL. They are all fantastic, but they are also overkill if all you want to do is refresh your Lisping chops. They all require absurd amounts of info hunting, mailing list searching, package installing, irc lurking, etc.

Dr Scheme just installs and runs. I finished the first 3 chapters of SICP four and half years ago using Dr Scheme. Nothing was more profound than defining a Scheme evaluator in itself. Once you get your head around that you'll have a lot more patience for the industrial strength brethren.
