£25 seems a bit on the cheap side for an annual sub too. My advice would be to look for a provider who will offer you a monthly sub. If you get any problems, or they shut down etc, the most cash you risk is one month's worth.
Before I receive any sort of negative feedback for that - please don't take anything away from the quality providers who provide an up-front annual sub - there are decent, honest folk out there. It's just my preference and 2 cents worth ;).
