Just noticed that Comet are selling these online at £299. Are they any good? I still haven't decided what to get, though I'm currently leaning towards the Pioneer 420, but how does this one compare? I'm always happy to save £100 - so long as I'm not getting a lemon. The Sharp website seems rather light on information, so I'd be grateful for anything anyone can tell me. Incidentally, the Comet model is DV-HR300F, while elsewhere it's found as DV-HR300H. Is there a difference?
