I used to do the same thing using aol(dot)com and aol(dot)ca but I haven't tried them for a while since using Startpage.
I see different results at Foxstart(dot)com, but they too are different than what I see at Startpage. G* is definitely working from several sets of data from the way it looks. I have followed the Foxstart differences for a few months in trying to work out a penguin filter, no luck yet though.
Doing a site:example.tdl search for a site we know was affected by Penguin.
G* - 185 pages
Foxstart - 138 pages
Startpage - 145 pages
And for a specific search phrase filtered out in April 2012.
G* - End of results (-950 penalty)
Foxstart - Page 2 (12th)
Startpage - Page 5 (55-ish)
Not sure where the difference comes from... data? Personalization of some kind? Not exactly sure, but very interesting and worth keeping track of in the realm of changes.
