We've never done SIG either, but there was a thread about it a few years back here: http://giftedissues.davidsongifted.org/BB/ubbthreads.php/topics/70563/1.html

Really, I think that only one person whose kid had been posted, but it was something. She seemed to agree that the math courses weren't as academically challenging as would be desirable.

I found a few other reviews online as well:
