For your ISP:
Netzero.net with free ad supported internet access up to about 10 hours a month and about $11 or so a month for all-you-can-eat access wthout the ads.
I just signed up with highstream.net at $8.66 a month for all-you-can-eat if you go monthly or less if you pay quarterly or annually. In my area there have been no busy signals and good connection speeds.
So somewhere between $29.99 up to $40.99 gets you two way satellite internet access with ISP.
I had the direcpc one way system where you use an ISP to upload and a ku dish to download. It was quite speedy late at night, but like any service, it slowed down in the early evening with everyone on the system. You can pick up a ku dish and the direcpc modem for a reasonable price on ebay.
I don't know if this BUD service is on ku or not. If it's on ku, you could buy a smaller dish (like a 30 incher) and dedicate it to your internet access and use the bud for surfing. It's still not a bad deal. We paid about $90 to get DSL hooked up.
