I my self am going for the excelsior class because I think it looks amazing, even without paint. That and if it weren't for the fact that Scotty sabotaged the transwarp, she may very well have been the fastest ship in the fleet at the time she was going through the testing phases.
as for how much the damn thing is gona cost, I am problebly looking at $20 or more, worth every cent. and I know what you are saying with the LEDs and the fiber optics, wow, just wow. way above my expirience level, but I am not afraid to try.
