Having had a few bad experiences with cheaper ISP's and being a fair distance from the exchange I decided upon recomendation to give Vispa a try. I was paying £25 or thereabouts for upto 1mb with an average speed of about 0.5mb.
Vispa were the only company that said "yes we can try and get you a connection, can't promise anything but if we fail you won't have to pay"
Which I though was pretty damn good, as it turned out I could get a connection just not a fast one which is more a problem of where I was living at the time than the ISP.
After I moved house I went back to cable as it was the fastest available option, the service and tech support with the big boys is just absolutely sh*t (I work in IT and so resolve my own issues were possible) and can not even be considered to be in the same league as Vispa who are in my opinion the best ISP out there, if they ever offer fibre to the kerb I will be the first to migrate.
I rated these guys 10 for speed not because the line speed was fast but because they got me the fastest speed possible when all other companies said I couldn't have broadband and 10 for value because for £25.00 the service given was absolutely brilliant!
If you pay peanuts you will get monkeys!
