I'm currently visiting my parents, they live on a farm in the middle of nowhere, my parents got the wireless highspeed internet from a local ISP a year and half ago, it's $49.99/month and 2mbps down, it's actually quite stable, plus they don't have bandwidth limits (yet), and dealing with their tech support has been great so far (the modem fried and they replaced it same day).
They only have 3 other options, they had 28.8k net for $27/month, which was a rip off by the phone company, there's another local high speed wireless company that sells service of 256k or so $50/month plus 1GB bandwidth limit, and a satellite provider that offers the same for $10 less, and that's all. My parents are really happy with their high speed internet, and so am I, I find everything quite speedy and stable.
For my personal internet, I have 6mbps internet with a cable provider for $39.99/month, I've been with them forever, for a while, every 6 months they kept upgrading speed, but now days, nothing, I find that I'm paying a bit too much for what I'm getting, for $10 more I could get similar speed, plus an xbox 360 for $99 with the phone company, but I will never deal with that company ever again. phew
