I'm going to save this one and study it, too.  I'd like to learn
to use regexes better, even if I do try to avoid them when possible :)

This regexp is fairly close to the one I used, but I employed the re.VERBOSE flag to split it out for readability. The above breaks down as

 [ ]*       # optional whitespace, traditionally "\s*"
 (\w+)      # tag the variable name as one or more "word" chars
 =          # the literal equals sign
 (          # tag the value
 [^",]+     # one or more non-[quote/comma] chars
 |          # or
 "[^"]*"    # quotes around a bunch of non-quote chars
 )          # end of the value being tagged
 [ ]*       # same as previously, optional whitespace  ("\s*")
 (?:        # a non-capturing group (why?)
 ,          # a literal comma
 |          # or
 $          # the end-of-line/string
 )          # end of the non-capturing group

Hope this helps,
