my LBS installed my stem in 'newbie' position. it's a Ritchey stem that can be flipped to be either higher or lower. i'm actually thinking about flipping it lower, which will give me some more reach and also get me more aero. at the price of back-ache comfort though, so i haven't done it yet.

if you've got road bike bars, you could rotate the bars upward a little, which would make the brake hoods higher (which is where you ride the most probably). that's free, which is better than buying a new stem. if you've got hybrid or MTB handles, that's not an option.
