The Specialized Allez is a great, solid choice for a first road bike - the geometry fits most people and it's decently light as well. The frame is aluminum with carbon forks, which is pretty much the industry standard for entry level road bikes (though I ride a steel bike w/ carbon forks - I find the ride is nicer). The Felt F90 also has an aluminum frame w/ carbon forks - however, it has a double crankset (only two gears in the front instead of three) which will make hills harder to climb if you're used to dropping down into the small chainring on slopes.

Lemond is basically Trek; they're the same company and the components are very similar.
