I developed a website for a company who had business broadband with Tiscali.
Would recommend against it as the domain management (ie name servers, DNS and mail settings) is virtually non-existent so looked at transferring the domain from them, but dealing with their indian call centre and customer service in general was awful and it took weeks to be able to do this.
Was a really bad experience and the company have now, after several more issues with Tiscali, cancelled the whole service with them.
If you are looking at setting up a domain and website, the best bet is to go through a good domain provider that give you options for configuring your domain and ease of management. Someone like 123reg.
Otherwise you might find that it actually becomes difficult to do anything useful with the domain.
As always there are good and bad stories for everything, but this was a nightmare and if you're looking for a flexible manageable solution going forward this would not be the way.
