Confused on road bike sizing?

I've looked at several guides and the more I see, the more I become confused. I am 6' 2"ish. Using the measurement guides on http://www.sierratradingpost.com/lp2/bike-fit-guide.html which has you a hold a book up to your crotch, I have a 33" inseam, a 27.5" torso, and 25" arm length.

According to this guide, I should buy a 56cm road bike. Many other guides, like http://www.bikesdirect.com/products/road... and ebay's guide have said that for that height and inseam, I should have a 60-62cm. http://www.bikecyclingreviews.com/faq/10... tells me 57cm and that I apparently have freakishly small legs for my height. Please help!

I don't know if it will help, but my jeans have a 34" inseam and go one inch past my heel, so the 33" seems to be about right. Thank you to everyone who tries to help

Also, this will be my first road bike, and I plan to buy it used on ebay, so, unfortunately I will not have the luxury of a test ride. Thank you to everyone who tries to help
