I liked the idea of them using Basestars, Raiders, and Heavy raiders. They don't need a thousand ships for a thousand reasons. Seeing as how they have ground troops they're rather like the colonials. Colonials=Battlestar, Raptror, Viper. Cylons=Basestar, Raider, Heavy Raider.
This makes sense. BSG is a drama first, not a total scifi show where they constantly revise the continuity and add in more flash.
