Hi Mike,
I'm basically on the same boat as you. I've spent the last few months researching to death what bikes are available, along with pros and cons on brands, steel, alu, carbon, shimano, campy, shram, etc.
It really comes down to personal preference, and most importantly frame fitment. So I would highly recommend getting out there and trying out as many bikes as possible. I'm at the stage of choosing a number of bikes to test ride, from the 500-1100 mark, just to give me an idea of whats available and how it all compares. Online reviews are a great tool, but as we all differ in sizing, shape and posture, they may not always be as accurate as you might think, i.e review 'A' for bike 'x' might be average, however it may actually be superb and a great fit for you.
I've got 2 bikes in mind which I'm torn between, 1. a steel bike which aesthetically ticks all the right boxes and rides and fits really well, but the components could be better, and 2 a alu/carbon bike that has great components, but aesthetically could do with a few changes - I'm still yet to test ride it though..
Another thing you might need to consider, is that the 2013/2014 season is coming to an end, so your choices may be limited. It also means many manufacturers will be introducing new models in the coming months; new colour schemes / components, new models and also possible discontinuation of current models / frames. So just be mindful, if you find a model that you like, your size may or may not be available, and you may need to wait for the 2014/2015 model. To my disappointment, the bikes I mentioned above, seem to be no longer available in my size - which just means I'll have to keep digging around or wait for the new release, I just hope they continue one of the bikes above into the 2014/2015 range.
Hope this helps, and enjoy looking for 'The' bike!
