Alternatively, you could try the free version of Lispworks.
Maybe you would be shunned if you showed up at a professional CL shop for using such a setup, but if you are just wanting to try out CL for personal learning don't let emacs stop you.
Lisp is great. It's so much fun writing Lisp. Coding Lisp with Emacs/Slime is almost an enlightening experience.
However, I never quite got over the frustration that writing the same thing in C++ gives factor two, three or whatever speedup. There is not much that can be done about this, I'm afraid. It's a tragedy.

- Found a typo in the acknowledgement section, you managed to misspell Robert Strandh's name :D
