Entry level is 900 to $1500 at non sale prices.
At this level you can get something in aluminum with a carbon fork and at least a Shimano Tiagra level drive train, maybe 105, which is the next level up. (Besides Shimano, SRAM and Campy also make respectable drivetrains) Stay away from low end Sora. Spend a little more to get carbon rear seatstays that absorb road buzz, which can be annoying and fatiguing. Trek, Specialized and Giant are the biggest names. Felt, Blue, Scott, and Lapierre are not as common, so you feel less like you are owning a Camry.
I assume you are not really racing, just want a fast road bike. And I don't know what you mean by "other people"
You will sell yourself short if you don't also test-ride the steel bikes from Jamis, Bianchi, Gunnar and Soma. Steel has much better vibration absorbtion than aluminum frames at the same price level, maybe 1/2 lb heavier.
However if you know snooty "other people", you'll also need to look at full carbon frames which is all the rage, (min. $2200) BUT put a ding or crash these once and that may be all she wrote. Steel is at least repairable usually.
