New Bike Need Opinions Fast

Plus another "75-100 dollars for shipping." I'm in with the Bear on this one...go down to your local bike shop and see whats there for the same money. If you get a standard road bike, you can add aero bars for what you would have paid for the shipping. Plus you'll get a warranty on the bike, they'll spend time to make sure you get the one that fits you, it will include pedals, a seat, and wheels with new tires. I'm an ex-bike racer with 30 years experience, plus a bike mechanic for the team I was coaching. The only way I'd buy this bike on Ebay would be if I could get it for the starting bid of $75 (which you can't because it won't meet the reserve). I'd look elsewhere and avoid the headaches this deal will end up costing you.

What may seem like a "bargain" will only wind up costing you over $1000 to bring it up to speck.  Go see a Cervélo dealer ... you can get a brand new 2004 Dual with full Ultegra for $1499; there will be no shipping, no assembling and you will be properly fitted on it by an expert!  The Dual is more than just a good beginner tri-bike, stock Duals have been used by pro triathletes in Ironman competitions who merely switched the wheelset. 

I would recommend buying a new bike from a local bike shop. They will fit the bike to your frame, and you will be able to test ride the bike. In addition, most bike shops will do free tune-ups for the life of the bike or at least for a couple of years. If you're looking for a deal, try to find a 2004 model. There are still a lot of them out there. Best of luck!

I got my brand new Cannondale r600 tripple for under $1000 with pedals and shoes... Check out the LBS.

Keep looking. Wheels will kill you pricewise, but if you keep your eyes open, you can get a used Tri-bike with full Ultegra for $600 on th'eBay.

Height alone may not be an adequate indicator of similar size. I'd ask them some questions on inseam, armlength, etc.
