i too was interested in gettin into road biking and had a $1000 budget. Then i test rode a Jamis Comet and i was like WOW! I spent $500 more ($1500) but got a $150 voucher to purchase instore items like pedals and shoes. I got my ride at Performance bike shop, a store here thats in my area
Heres the link to my bike

PerformanceBike Online
I didnt buy the bike online tho, just locally. Performance also offered life time tune ups, so when my gearing gets whacky and stuff, the adjust it for free as long as i own my bike.. i like that!
