We really need more info. It has been asked so doesn't bear repeating. How are you going to use it. It's different if you want to race or may just want to ride comfortably and maybe commute once in a while.
I WOULD not buy my 1st bike from ebay or online. I am tempted to say Neuvation, but how is he gonna handle it if it doesn't fit? Fit is a huge issue for newcomers to cycling and an ill-fitting bike will drive you away from cycling quickly. (Neuvations are basically knocked off Cervelo soloists by an online brand that is reputed to be a great cust svc e-tailer.) See interview with John Neugent at testrider.com
I consider $1500 for a road bike alone to be a sort of no-man's land price point. That's just me, though. There are a zillion little accessories you are going to want/need so I would go entry level or maybe entry level with some better components like 105. You can prolly get a decent aluminum frame from an lbs with 105 for around $1200, especially this time of year. Or you can go down to sora components for about $600-800 on entry level and spend the difference on all the accessories with some (a little) left over. Shoes, pedals, bibs, replacement saddle, computer, seat bag, blinkie, bottle cages, frame pump/co2, light. The siht adds up quick.
I think this time of year you may be able to beat someone down (sorry shop owners) to about $1100 for alum frame with complete shimano 105 and maybe pedals, cage/bottle and a cheap computer. The important part is to know what and how they are going to do to make sure the damn thing fits you correctly. Otherwise they could give it to you for nothing and it still would be a waste. I'd shop now before it warms up and he isn't willing to deal.
