I'm after a UK-based MS Sharepoint Services account, ideally on a shared server to keep costs down.

I notice that the usual players (1 & 1, Namesco, WebFusion etc) all offer these for around 15 - 25 monthly. Has anyone got any experiences of them, or can suggest other alternatives?

I currently use Clook for Linux-based hosting, but I have a client who wants an Extranet, and Sharepoint seems by far the easiest and quickest system to satisfy their needs... so if anyone can suggest a Windows host who's half as good as Clook, that would be a start!
