there are lots of great bikes out there in your price range... I know a friend of mine just got the Lemond Buenos Aires for $1400 out the door... 1/2 steel 1/2 carbon fiber with Campy and a triple... a very, very nice bike for the money! She absolutely LOVES this bike.
definitely buy a bike that fits (critical really) and buy the best frame you can afford. The components will probably be decent and can always be upgraded when you can afford it... but the frame is the frame you'll have til you buy another bike someday!
my only other recommend is to ride every single brand you can get your hands on until you find the one that is your favorite! I was SURE I was going to buy a Trek Project One WSD... but they just didn't work for me, weren't comfortable no matter how they tried to make it fit... so I started riding everything else... and one day I rode the Lightspeed... end of story! LOL... for ME... it is the perfect bike...
good luck and happy shopping!
