Which way to get Broadband?

Hi all,
Having had many problems with my ISP support I want to
change supplier, but to what?
I would ideally like fibre broadband only (no land line included)

The only way I can get fibre here on the Isle of Wight is with BT with
a land line phone line included

I found a Satellite broadband only supplier but they will supply a
self install kit only, and I would sooner pay for a survey first to
make sure it is in sight of the Satellite as I am in a built up area!

This leaves the choice to either SKY Satellite or other like: Talk
Talk or Virgin
As I know very little about them any thoughts welcomed.
