Besides $1,500, what's the difference between the P2c and the P3c? I have been told by several people that the aerodynamic difference of the actual bikes are negligable. Is it worth over $1,500 for the P3C? Does anyone know how to find out the potential difference in aerobar height in the two bikes? Couldn't a special type of drop stem minimize this difference? Even if you paid $100 for a stem, it would save you a big chunk of change over the P3C.

I'm not trying to knock the P3C, or people who buy the bike. I'm about to shell out some bucks, and I don't want to buy a brand new $3000 bike and constantly wish that I spent the extra $1500.
