Have you gone beyond your local phone company and checked for DSL availability. Like on DSLreports.com. There are are some companies out there offering a wireless DSL connection that doesn't use teh phone lines and is cheaper then what you said you'd be paying for the sattelite. Of course not every area is going to have it, but it's another thing to look for if it's available.
Also, thinking big now. Do you live in a subdivision/bedroom community, or just out in the sticks? If there are a lot of houses out there in a small area with people in the same boat as you maybe you can get a T1 line and split it with a bunch of neigbors. Be your own ISP.
