Realistically, entry level road bikes start at about 700 and run up through about 900 depending on manufacturer. They will all have some combination of Tiagra and Sora components. In the end, one of the bikes will speak to you when you are test riding them, that is the one you should get. Remember to budget for shoes, pedals (assuming you are going clipless), and water bottles/cages. It is possible to get a good deal on CL but you will have to shop wisely, and if you need to adjust the fit (different stem, etc) that will cost extra as you will have to go purchase a different stem, whereas if you buy new from the LBS changeing the stem and such is included. As an example, I bought a Cannondale CAAD9-7 (entry level in that series) and by the time I scored shoes (on sale), pedals (Look Keo Classics) and a couple of cages & bottles, a tube, patch kit etc it was about 1150 out the door with the bike representing about 875 of that.
