I almost forgot, in your price range, you should be able to find the following:
Specialized Ruby Elite or Amira (Amira more aggressive than the Ruby)
Trek Madone 4.5
Giant Avail Advanced (carbon)
Cannondale Synapse

The ones above should come outfitted with Shimano 105 or comparable SRAM.

I also rode an Eddy Merckx, Orbea, Felt, Bianchi (all were carbon) but they were pricier than my previous suggestions.

I definitely needed the WSD as I have the common short torso, longer inseam in addition to wanting a more relaxed geometry. I rode several non-WSD bikes in my size and felt very awkward on them. Oh, the other thing is bike sizes. I tried sizes ranging from 48cm to 52cm. Some of the "smaller" bikes felt larger than some of the "bigger" bikes. It truly depended on the manufacturer and the model.
