If you aren't opposed to watching TV, I can highly recommend the COSMOS series (remake) with Neil DeGrasse Tyson. It's relatively affordable on both DVD & Blu-Ray and has around 13 hours of viewing. A wonderful series.

It's also available through other sources ;-)
As far as books go, I found great value in the following 2 sources, one which I bought for my son, and the other for myself.
