Give it a few millenia and BT will actually get rid of their pathetic copper lines and replace it with fibre optic, then we can all have OC-3 speed at almost no cost to the operator. The only problem being that the rest of the world would have to be just as fast to enable using such bandwidth.
Helz, go for ISDN, that's what I did until broadband reached me. £2k, is a little over the top for Satellite, you can get one way services for less than £20 per month, but there are various limitations, such as port blocking and it doesn't work with all protocols, but even two way Satellite is available for under £80 per month.
You could also wait until the electricity suppliers perfect delivery of data via your electricity supply. It has actually been possible for years, but there is very little development going into it, although Scottish Hydro Power did run trials a few years ago.
Another alternative is to wait for mobile technology to increase data speeds, then use your mobile as your modem, although if the current data prices for mobiles continue, that would be an expensive option.
If there is enough interest in your area, you could get a carrier mast set up locally, which would have to be privately funded, then you could use a wireless ADSL system.
At the end of the day, there are options available to you, if you don't like them, move house.
