agreed! , equipment priced "in-between" keep in mind "ease of operation" and "compatibility" with a computer.
i would also advise speaking with someone/site/etc. who's photography interests you! , they may be able to help you further!
i would not suggest anything used , most likely you are dealing with someone else's problem and/or in the event you don't like/not working you can always return it with reciept.
