Thanks, Jason. I did download that one first (1.19 meg 
Aspell-0-50-3-3-Setup.exe) but then found the other 0.60 version (aspell 
binary only). Can I install the 0.50 and then copy the newer file(s) on 
top of them? All my GnuWin32 tools are in a flat directory C:\gnu and 
this is included in my PATH, but after winnt/system32. Name collisions 
like sort, ftp, etc. will try to run the MS versions first.

So is this on the right track then:

(defcustom ispell-program-name
  (or "C:/gnu/aspell"
      "ispell")
;; anyway (or "this" "that") returns "this" without error in scratch

weren't there.
;; maybe this is a better guess:

(or (locate-file "c:/gnu/aspell" exec-path exec-suffixes 'file-executable-p)
      "ispell")

"Program invoked by \\[ispell-word] and \\[ispell-region] commands."
  :type 'string
  :group 'ispell)
