Mike, I hate to burst your bubble, but that is precisely how Ancestry set up their business model - bait is the name of their game.
Susie, add jewishgen.org to the sites that Eddie mentioned. That is free, but you have to sign up for an account and the "price" of the free account is that they'll pester you unmercifully with emails begging for donations. By the way, not a whole lot of people seem to be aware of this, but jewishgen is now owned by LDS, which seems kind of strange to me.
