Eh, no. You have Elisp+cl-lib but SBCL too, and you can use Sly wth SBCL.

Huge tip: if you use MCCLIM, install Ultralisp first and (ql-quickload 'mcclim) later: it will give you a big speed boost. Big, not as the ones from Phoronix. Actually big. From 'I can almost see redrawing on a really old ass netbook' to 'snappy as TCL/Tk' under SBCL.

As you can see, you don't need to pay thousands of dollars.

For Scheme, S9 just targets R4RS but as a start it's more than enough, and for SICP you can install Emacs+Geiser+chicken Scheme and from any Linux/BSD: distro command prompt, you run:

       sudo  chicken-install srfi-203
       sudo chicken-install srfi-216

      (import scheme)
      (import (srfi 203))
      (import (srfi 216))

       csi yourfile.scm 

       chicken-csi yourfile.scm

         M-x install RET geiser-chicken

 if you are lazy. You can install the SICP book with

        M-xpackage-install RET sicp

       M-x info RET

      M-x geiser
