the campy two-bolt styles have setback, but they're pricey. i sold one in that size this week on craigs for $60.

the one-bolt kalloy types on ebay are less than $16.

i've never needed more positions than the one-bolt styles like the laprade offer. and i've found them much easier to position than the vintage campy record two-bolt design. but the campy ones are so much more posh.

there's also a s600 seatpost on ebay, but it's a one-bolt, like the laprade.
