The critical measurement is your inseam.
If you have long legs, a WSD may be right for you. If not, you may find the WSD a bit too short in the reach.
Go visit as many bike shops that you can and test ride all the different models. Trek 4300's are good, but every manufacturer makes a good bike in that price range.
Check out Gary Fisher bikes. Trek owns GF and so their specs will be similar, but the frame geometries will be different.
I'm a big fan of Specialized bikes.
I would avoid Haro bikes as they tend to be a bit overbuilt and will be heavier for you.
