FYI for what it is worth
In the under $1000 range the 2 entry level road bikes that got the best reviews in Bicycling Magazine are the Trek 1000 and the Specialized Sequoia (both run around the $7-800 range)

I am into touring and not racing so I got the Sequoia for a little smoother though heavier ride. it has seat suspension and "Zertz" on the front fork (Zertz help absorb the road chatter for a smoother ride w/o full front suspension like on a mountain bike)

I would seriously look at the Trek if I was more into speed than comfort - it was listed as the best road bike for under $700 in Bicycling Mag June 2006 page 94

Just my opinion
I LOVE my road bike and although hybids are versatile and my BF rides one AND rides it well and fast (I shudder at thinking of trying to keep up w/ him if he gets a road bike) I would NEVER give up my road bike - I keep my old mountain bike around for when I need it on rougher terrain
