I've got
this list of the ones we know most about on these forums. On that page there is a link to a spreadsheet others have produced that is very good.
I went to IDNet a year ago. As a light user the price compared to the Infinity price at the time was close enough if you/I paid the year up front.
BT have since brought their prices down, and Plusnet have come onto the market with their Value Fibre and Extra Fibre products. I've just migrated to Plusnet Value Fibre (9 days ago) and so far quite happy. Upload is only 2Mbps where IDNet was 10Mbps, but I'm saving an awful lot of money! It was a toss-up between Plusnet and Infinity 40GB.
