Magix Movie Edit Pro 11: $29.99 - $30 in 2 rebates ($10 instant, $20 mail-in) = FREE at CompUSA
Even without the $20 mail-in rebate, the price out the door is $19.99 plus any applicable taxes.
For full disclosure, Magix has a new version available: Magix Movie Edit Pro 12. Although I believe the new features aren't much to crow about. The only notable improvements are Magnetic objects (Automatically set decorative elements, picture-in-picture and text objects to follow moving objects in the background video) and possible improved MPEG-2 editing support for those people that edit with the (MPEG-2) VOBs directly.
