I think people are missing the point here and recommending stuff that is not needed. The OP said its for a
starter dslr, plus no mention has been made of type of photography needed.
Why a starter would want a 50mm is beyond me unless they were very serious about this and looking to do some creative stuff.
My brother in law recently picked up a Canon 1000d with kit lens, was looking at that or Nikon D3000 which I suggested but he preferred the feel of the Canon. Both are very similar and good starter cameras. All he wants at the moment is to have a better quality camera than a compact for taking pictures when out (currently on honeymoon in Thailand) and of friends/family. He will be taking everything on Auto and saving to jpg. Nothing wrong with that (it did me fine on my D40, until I was bitten by the bug!!)
If he is like my brother in law then its far better to go to jessops or similar, try the camera, and get it from there. If however he is looking at this from a 'photography angle' rather than a replacement for a compact, then by all means, start looking
second hand and at 50mm etc...
