Eliminator makes a whole slew of canopy cats ranging from 25' to 36' Daytonas. Their first canopy cat came out I would say around 99 or 2000 with the 36 Daytona. Currently they have a canopy version in a 25, 26, 27, 28, 30, 33, and 36. When you go from the 27 to the 28 you go from single power to twins. Take a look in the classifieds here on oso and also traderonline, there are tons of them.
I believe they started making the canopy 30" Daytona in 2001. Actually Eliminator calls their canopy boats ICC's. (Integrated Cockpit Canopy).
