You can always look at an allez expert or race if you decide to go high end alu. I wouldn't though. The want for carbon will eventually settle in and you will be stuck with a 2000 dollar aluminum bike, not good. get something like a z85 if you are just starting or maybe a lower end caad or allez (I believe the z85 is the best bang for the buck). When you know what you want sell it for a minimum loss and BAMMM get youself a freakishly awesome 10k dollar carbon bike.

I had a z85 for about 4 months until I decided to jump onto the roubaix. While the roubaix was an awesome machine I chose it based on my neck problems. Now that my fitness level has increased and I barely use my neck, I wish I would have waited a bit longer and gotten that Venge I wanted. Crap happens. I start racing this season and if everything goes well next year or on 2015 I'll buy myself the S works Venge I really want... Who knows, by then it might even be another bike.

Good luck and take in mind that right now you dont know what you want so choose what fits you best right now because your riding style will change with time and you will eventually figure out what kind of bike you need instead of want.
