Some other companies I like:
Veritas Press
Area 127
Curriculum Click - I found a great download for printables (household and school) on this website called Master Planner. It had 160 different printables for about $7.00 and it was totally worth the money.
i also like: Memoria Press, Veritas Press (as you do), Pennywise Learning, Peace Hill Press and Bolchazy-Carducci Publishers (for Latin and Greek material)...
