It looks like Red-Gate SQL BAckup is a great deal.  We have servers located at branch offices on low quality DSL lines and need to bring a backup to HQ on a regular basis and also to a disaster recovery location.  We are located in 11 different countries in Latin America and highspeed connections are very expensive.

While backup speed is nice, compression is our most important factor.  What program woudl provide the smallest compressed file? I don't mind using out of the box SQL backup and then compressing with a ZIP program if it gets a smaller file.
