The joy of thinking [videorecording] : the beauty and power of classical mathematical ideas / Edward B. Burger and Michael Starbird.
Ed Burger does many of the Thinkwell math programs. He's another engaging teacher. Can't beat the price from the library, that's for sure!
To echo some of the other sentiment... don't pay full price for one of the Teaching Company tapes or videos. Instead, get yourself on their email list and be patient. Also check the retailmenot.com website before ordering, as you'll often find another coupon that you can combine with your purchase.
