Well, there's a good review
here, Sam, and the majority of
Amazon customers seem to like it.
As for the five year warranty, I certainly wouldn't recommend you buy it, but shop around and get it free! John Lewis will price match, and offer the free extended warranty, so if you can find it at a good price, and there's a JL nearby, it's worth the effort. There will also be other dealers who offer the 5 year warranty, including
PRC Direct (but you have to purchase in store), and others, if you Google, but I would advise the JL route, if you can.
