I paid $450 shipped for my koni yellows on Honda-marketplace.com

If your happy with your S tech springs, pair them up with the Konis for now. If you ever want to upgrade to coilovers or a stiffer spring, the shocks are adjustable and will accept either.

Last I checked bilsteins were a bit higher in cost, and offered no adjustability. I have them on my truck, they are a well made product but I still think konis are better for the integra.
