Abeka This is good for science, I'm using the Grade 1 level with my JK son.
My Father's World This is also very nice. I have the Kindergarten stuff on loan right now but opted against it and am using Weaver instead.
Five in a Row I have this but haven't used it yet.
Tapestry of Grace Looks great but seems like a bit of work.
Sonlight This is a fairly popular one. I don't buy their stuff but do enjoy the newsletters and will sometimes use their book list at the library.
Vision Forum I've listened to several of their CDs and have really enjoyed them.
