Does can anybody give me some advice on broadband internet access in the Murkle area. It is a few km from the nearest telephone exchange, which I believe will reduce the available bandwidth.

From reading Which reports etc. there are many ISPs offering broadband internet access, but from my understanding of the subject, the ISP has to have its communications equipment installed in the nearest telephone exchange to be able to offer broadband (is this correct?), in which case it is likely that a lot of these ISPs won't offer broadband in rural Caithness.

What ISPs do offer broadband in this area, and which gives the best value for money?
