I use Eclipse, which I see is also near the bottom. The only complaint is that they have periods when web-mail is inaccessible occasionally, presumably during upgrades. But spam now virtually non-existent, pre-filtered by them. Not an advert in site anywhere.
If anyone knows a service that is cheaper (after expiry of intros) than £15/month inc VAT, do tell. The support is in Exeter, where spoken English is quite good and reply to e-mail support tickets within a day or so. Speed is dependent on our lines, about 5 miles from the exchange and shared.
Also unlimited landline phone calls for £6/month.
Probably not as good as cable systems, but will get seriously worried if they start digging trenches up here.
