You can buy a Bacchetta CA2 frameset for $2400 (needs a $250-$450 seat and an uncut fork)
the Cervelo S5 is $3500? can't remember, but I lust. I lust! Although, the CA2 is quite likely closer to being in my stable than an upright. UUUUUGGG! too many bikes, not enough time. mmm a P4. mmm an Avatar. Mmm a Go One. Kinda want Tim to build me a tilting delta trike, too. stay on target.
Carbent frameset is $3700? or so, but comes with a fixed seat.
