I've been with Eclipse for 12 years - absolutely no complaints at all. They are Exeter based, their tech people (no scripts used!) are also Exeter based on a standard charge phone number and really know what they are talking about. On the few occasions when I have had a slow connection - I'm miles from the exchange so slow anyway - they have sorted it efficiently and I've never felt rushed in dealing with them.
Certainly not the cheapest by any stretch of the imagination but you get what you pay for. I also have a domain name hosted by them which I only use for a more personalised email address and the transfer of that from GoDaddy to them was handled without any problems.
Edit: Having not been on their website for ages it seems that they now don't offer residential contracts but do offer a Home Office option at the same price as I'm paying for residential.
