Wow, this was the first time that I ever saw someone mention Cruise Chaser Blassty! I don't know much about it myself, but I do remember seeing models of this in some old late-80s issues of Hobby Japan.
The fighters in Gall Force are quite cool, my particular favorite being the Solenoid fighters from Gall Force 2.
One of my favorites that hasn't been mentioned is the F/A-37 Strega from the Playstation game Philosoma.
As a few people have mentioned, I also like the Starfury and Thunderbolt from Babylon 5. Mostly because out of the ones that have been mentioned, they are the most realistic. Other than the weapons and powerplant, the Starfury could actually be built with our current technology.
