Thanks for all the help. I read many sites dealing with fitting, and tried some of the online fit calculators before I posted this. I guess I wasn't really clear in my question. Sorry for that.
What I'm wondering is are the majority of online fit calculators (such as WrenchScience) geared for nose to stem speed racers? If so, how can one interpit the results for a more upright posistion/comfortable ride? It really bothers me that I can't try/look at a bike before I purchase it. Thanks.
