Replying to Thoughts on used or refurbished cameras (HV20/HV30)

Hey guys. So I'm considering purchasing a HV20 or HV30 for the season and for financial reasons am trying to get it at a more affordable rate and thus am looking at used and refurbished ones (especially for the HV20 since I can't really find any brand new ones anymore). I was just wondering what my best bet would be in terms of should I just lay out the extra couple hundred for a brand new one or if I'd be alright with a used/refurbished one? What sort of risks may I be looking at running by purchasing them? Sorry if there is already a thread relevant to this somewhere. Thanks for the help! +++Karma
