Home-Schooling HS Spanish Courses?

Hello,

For anyone who has taken A Beka's HS Spanish 1 or 2 AND those who have taken Bob Jones University's Spanish courses, please read on.
We are trying to find a good Spanish three course that will work with and follow up on A Beka's two year course that we have taken. Does anyone know of a HS Spanish THREE course that works well with the A Beka series? If so, please tell me the name of the publisher and licensee.
Does the B.J.U. Spanish three follow well after A Beka's?
If you have taken the B.J.U. course, could you tell me if you enjoyed it. Did it seem superficial or was it a thorough, challenging course suitable for high-schoolers?
Any comments, suggestions or caveats regarding Spanish Three Courses is welcome.
