Thank you everyone for your responses. I\'m still interested in any other experience buying used, and any experiences in dealing with Sharp.
Thank you Rikiya - while I\'m not looking at Japanese models right now, I have considered it. Your response in that regard is helpful. Thank you also Stu - I\'ll keep in mind the distributor aspect. I\'m pleased to hear, Adalberto, that Sharp solved your problem. It sounds like their support is very good, if this is the typical response.
I\'ve been very impressed with the overwhelming helpfulness of everyone here in the Zaurus User Groups. I\'m determined to get a Zaurus now, just so I can contribute something!
I\'m considering calling Sharp to ask them about their warranty policies. I will post the result here if I\'m able to get a statement on this issue.
Thanks again everyone!
