Agree with JayDay. Alternatively, do you know anyone (very) nearby who has wireless? They might be prepared to share it...at some cost to you...but then you'd probably need better kit than 'normal' wireless, so the cost would be more.
What's wrong with a landline?
Either that or cable internet if you can get it in your area.
All the providers do them. Vodafone has lately launched "3D Broadband" as it calls it, which is even quicker. If you got the right tarriff, and didn't use it too much, it might not be so bad. Make sure there is coverage in your area.
The alternative, as mentioned above, is to use a mobile phone. Your mobile might even be 3G in which case it would be pretty quick. Again, best to make sure you aren't paying silly money by getting on the right tarriff with a certain amount of data included, and probably not right for relatively heavy usage.
