i was with pipex for years, but last month switched to orange. Unimited broadband at appox 2mb (i'm a few miles from the exchange) for £10
it could have been up to 8 if i was closer.
Pipex service was relentlessly reliable, although i was paying £24 for the same package as i'm on now.
you can haggle with them a little, but i think that may only have been because i was a longstanding customer.
SO far Orange has been fine, though i'm less enamoured with their mobile phone tariff! no gprs allowance, and mms is charged seperately from allowance!
with O2 i had 1mb download, and an mms counted as 3 texts, which i had 600 a month of...
wish i'd never left them after 5 years now...
