best source of accurate insider ownership data?

[cash_incinerator]

does anyone have a source they prefer for insider ownership data on individual stocks; on various publicly available sites, i'm getting wildly divergent responses and I"m not sure how reliable they are

My favorite tool is openinsider.com but I always check the SEC website for companies manually and read the filing documents if I really care about accuracy.
