I got my girlfriend a KitchenAid for Christmas from JL. Superbly built, real tank like feel to it. There was a promotion on, so the mixer came with the metal bowl and I sent away to get the glass bowl FOC - I don't think she has used the glass one yet. There's been plenty of cakes done in the metal one though
Are you anywhere near a JL store? If so, you can possibly beat them down on a price little if a high-street retailer (eg
Harts of Stur) is cheaper. IIRC, JL don't price match against online only sellers though. I think I got the JL in-store price down by £20 to £30. Harts list the warranty as being a 5 year KitchenAid, so maybe that is standard?
