I also have the 150 GB/$120 a month plan and it is extremely expensive especially for a service that is 1/2 the speed of the FCC definition of Broadband (when I'm getting the maximum throughput). Also my two-year contract runs out soon and understand there is no equivalent package so to get something close it will cost about $250 per month or more. As a student in college that uses the service to stream my classes don't know what you expect me to do. :(
You can look HERE for what is coming in March of this year from HughesNet or wait for ViaSat-2 to launch and then to become operational. The ViaSat-2 will give more Internet for your money but Hughes will happen sooner. For the next 2 months you will learn patience while you decide what to.
Edit: Greg, you don't need to re-new your contract with exede. You'll be "month to month" after your contract term expires.
