I guess I might just do that. The green screen might make delivery expensive also. And looking at the description of the tutorial DVD that it comes with, I think I can probably manage without it.
For music, you should take a look at SonicFire Pro. It has a little side tool called Express Track which you can get for free (it comes with a 30d trial of the SonicFire). But the Express Track and 5 multi-layer tracks are yours to keep and use. It's amazing, watch the demo. Want a 22 second bumper? Just type in 22s, choose the "style" of the track you like and you've got 22s. The SonicFire app itself does some cool stuff, but the Express Track is quite remarkable. http://www.smartsound.com/sonicfire/index.html
