You might also try to find out if there is a homeschool fair in your town. By coincidence, a fair was taking place last year, right when we pulled our son out of PS. It was great, because I not only got to see the material hands-on, but I also got to meet other homeschool moms and ask their opinions.

We currently use:

Horizons Math
The Story of the World
Beka Spelling
Beka Language
Type 2 Learn for Keyboarding
Beka Our America
Beka Health
Brainpop Online (fun videos to introduce new concepts)
Real Science 4 Kids: Biology, Chemistry, Physics
