Get DSL and Cable then buy a Xincom dual wan router. This will support 2 different internet connections or 2 of the same. You can have static ips or DHCP or PPoe on one or both wan ports. It does load balancing etc and its relativly cheap. It works great in a business enviroment or for home use. The router is less than $200 and work good if you set it up correctly. It will work with ADSL DSL Cable T1 Satalite etc.
