For me, buying a 2nd hand DSLR is not an option, unless you know who they really are. Why?
1. No more warranty means no free services when something goes wrong with my equipment(s). If still got warranty, at least half a year to go than I'll buy.
2. All SLR/DSLR have a number of shutter life-span. When you go to check your shutter count at the servicing centre, it might be too late ( if it reaches 35,000 count or more) :dunno: already.
3. You do not know how well the previous owner used this item unless you know him/her well (like friends of yours who know their equipment well). So if something happens, there's still some compromises of agreement to be made between both of you.
That's all I have to say & all that mentioned above is to your references only. Thanks.
