For that sort of money I'd save up a little more and buy new. You can get pretty good deals on recently obsolete models like Canon's 400D or Nikon's D40 (amongst others) and you'll get a warranty.Actually saw that already... but its an auction and only ends 25th.
At the moment I can get a local 350D with 18-55 Lens for R3500, or CT based Sony Alpha 100 with 18-70 for 4k ... I'm leaning towards the Sony though.
