Some like leather, some like plastic. Some like Cytomax, some like Accelerade. Some like clipless, some don't. Some like fat tires, some like skinny. Etc. Etc.
George, many see this as an opportunity to "move up" to carbon. Ride a good steel bilke (right, try to find one to test ride-- I know) and then decide. In the end, a good bike is a good bike no matter the material. And the main thing is that your body is working, not that it's attached at the butt to the zenith of cycling technology. The differences may be noticable, but in the end they still stay marginal as long as the bike fits well.
Of course, we all want the most bang for our buck. Which brings us back to ride as many as you can, don't settle just because one is easier to get than another....but eventually, just like DG, you'll have to settle on one......and then relax into a nice marriage with your machine and forget other women, er...bicycles I mean.
