I think 50mm 1.8 too! Great lens for the money and it produces sharp images with nice enough bokeh. You also get to learn about photography using your feet and it makes you think about composition more.
I think you'd find it's a good first step on the ladder. 


Hmm, although I agree it's a nice beginner(ish) lens and at an amazing price, I wouldn't say any prime lens is a good choice for a first lens. A complete beginner will want and probably need the flexibility of a zoom. I know it's good for making you think about composition and such, but let's be honest - it's a bit harsh to force a new photographer to use a prime lens for everything.50mm prime f1.8
a great learning lens and down at the lower F-stops you can get some impessively shallow d.o.f which is often pleasing to the eye.
