A WISP is most definitely the way to go unless you have issues receiving the signal or if the WISP has issues themselves.

I imagine any new broadband satellite company that comes out will have few users on their bandwidth therefore might be a good choice at first until their pipe starts to fill up. Same thing with Hughes or WB if a new satellite slot opens up. They oversubscribe and since the amount of bandwidth usage continues to go up, they need to allot more space for the same number of users that they have.

I think part of the problem is that they are still growing in number of subscribers therefore they are concentrating less on quality and more on quantity. If subscriber growth was not so great and they had more customers leaving for poor service then they would be able to invest the increase in space they are getting to allowing more bandwidth for their current customers insteadof their growing subscriber base. 300-500 kb/s today is like 53.3 kb/s tomorrow.
