I agree with these but I have reservations with buy secondhand equipment. For mechanical equipment and simplier electronics--absolutely. But the problem with digitals (particularly high end) is that there's So Much to go wrong and you really don't know why the previous owner sold it. Maybe he wanted a newer camera maybe he knew something was goofy with it--something you won't see on an every day basis so he didn't say anything because he didnt' want to hurt the resale value. If you buy second-hand digital cameras make sure you get it from someone you trust and that there's a good warranty. Then try it out *thoroughly* as fast as you can to verify it's good.
